  • Chapter 19 - the Oscillator
    Chapter 19 - The Oscillator The Electronics Curse “Your amplifiers will oscillate, your oscillators won't!” Question, What is an Oscillator? A Pendulum is an Oscillator... “Oscillators are circuits that are used to generate A.C. signals. Although mechanical methods, like alternators, can be used to generate low frequency A.C. signals, such as the 50 Hz mains, electronic circuits are the most practical way of generating signals at radio frequencies.” Comment: Hmm, wasn't always. In the time of Marconi, generators were used to generate a frequency to transmit. We are talking about kiloWatts of power! e.g. Grimeton L.F. Transmitter. Oscillators are widely used in both transmitters and receivers. In transmitters they are used to generate the radio frequency signal that will ultimately be applied to the antenna, causing it to transmit. In receivers, oscillators are widely used in conjunction with mixers (a circuit that will be covered in a later module) to change the frequency of the received radio signal. Principal of Operation The diagram below is a ‘block diagram’ showing a typical oscillator. Block diagrams differ from the circuit diagrams that we have used so far in that they do not show every component in the circuit individually. Instead they show complete functional blocks – for example, amplifiers and filters – as just one symbol in the diagram. They are useful because they allow us to get a high level overview of how a circuit or system functions without having to show every individual component. The Barkhausen Criterion [That's NOT ‘dog box’ in German!] Comment: In electronics, the Barkhausen stability criterion is a mathematical condition to determine when a linear electronic circuit will oscillate.

  • AM Transmitters
    Chapter 4: AM Transmitters Chapter 4 Objectives At the conclusion of this chapter, the reader will be able to: • Draw a block diagram of a high or low-level AM transmitter, giving typical signals at each point in the circuit. • Discuss the relative advantages and disadvantages of high and low-level AM transmitters. • Identify an RF oscillator configuration, pointing out the components that control its frequency. • Describe the physical construction of a quartz crystal. • Calculate the series and parallel resonant frequencies of a quartz crystal, given manufacturer's data. • Identify the resonance modes of a quartz crystal in typical RF oscillator circuits. • Describe the operating characteristics of an RF amplifier circuit, given its schematic diagram. • Explain the operation of modulator circuits. • Identify the functional blocks (amplifiers, oscillators, etc) in a schematic diagram. • List measurement procedures used with AM transmitters. • Develop a plan for troubleshooting a transmitter. In Chapter 3 we studied the theory of amplitude modulation, but we never actually built an AM transmitter. To construct a working transmitter (or receiver), a knowledge of RF circuit principles is necessary. A complete transmitter consists of many different stages and hundreds of electronic components. When beginning technicians see the schematic diagram of a "real" electronic system for the first time, they're overwhelmed. A schematic contains much valuable information. But to the novice, it's a swirling mass of resistors, capacitors, coils, transistors, and IC chips, all connected in a massive web of wires! How can anyone understand this? All electronic systems, no matter how complex, are built from functional blocks or stages.

  • Unit I - Feedback Amplifiers Part - a 1
    EC6401 Electronic Circuits II Department of ECE 2014-2015 UNIT I - FEEDBACK AMPLIFIERS PART - A 1. Define positive and negative feedback? Ans: Positive feedback: If the feedback voltage (or current) is so applied as to increase the input voltage (i.e. it is in phase with it), then it is called positive feedback. Negative feedback: If the feedback voltage (or current) is so applied as to reduce the input voltage (i.e. it is 180out of phase with it), then it is called negative feedback. 2. What are the advantages of negative feedback? Ans: The advantages of negative feedback are higher fidelity and stabilized gain, increased bandwidth, less distortion and reduced noise and input & output impedances can be modified as desired. 3. List four basic types of feedback? Ans: (1) Voltage series feedback (2) Voltage shunt feedback (3) Current series feedback and (4) Current shunt feedback. 4. Negative feedback is preferred to other methods of modifying Amplifier characteristics. Why? Ans: Negative feedback is preferred to other methods of modifying Amplifier Characteristics because it has the following advantages of reduction in distortion, stability in gain, increased bandwidth etc. 5. State the condition in (1+A) which a feedback amplifier must satisfy in order to be stable. Ans: The two important and necessary conditions are (1) The feedback must be positive, (2) Feedback factor must be unity i.e. A = 1 6. What is meant by phase and gain margin? Ans: Phase Margin: It is defined as 1800 minus the magnitude of the Aat the frequency at which A is unity. If he phase margin is negative the system is stable otherwise unstable.

  • Variable Capacitors in RF Circuits
    Source: Secrets of RF Circuit Design 1 CHAPTER Introduction to RF electronics Radio-frequency (RF) electronics differ from other electronics because the higher frequencies make some circuit operation a little hard to understand. Stray capacitance and stray inductance afflict these circuits. Stray capacitance is the capacitance that exists between conductors of the circuit, between conductors or components and ground, or between components. Stray inductance is the normal in- ductance of the conductors that connect components, as well as internal component inductances. These stray parameters are not usually important at dc and low ac frequencies, but as the frequency increases, they become a much larger proportion of the total. In some older very high frequency (VHF) TV tuners and VHF communi- cations receiver front ends, the stray capacitances were sufficiently large to tune the circuits, so no actual discrete tuning capacitors were needed. Also, skin effect exists at RF. The term skin effect refers to the fact that ac flows only on the outside portion of the conductor, while dc flows through the entire con- ductor. As frequency increases, skin effect produces a smaller zone of conduction and a correspondingly higher value of ac resistance compared with dc resistance. Another problem with RF circuits is that the signals find it easier to radiate both from the circuit and within the circuit. Thus, coupling effects between elements of the circuit, between the circuit and its environment, and from the environment to the circuit become a lot more critical at RF. Interference and other strange effects are found at RF that are missing in dc circuits and are negligible in most low- frequency ac circuits.

  • Electronic Circuits Ii – Seca1401
    SCHOOL OF ELECTRICAL AND ELECTRONICS DEPARTMENT OF ELECTRONICS AND COMMMUNICATION ENGINEERING UNIT - I ELECTRONIC CIRCUITS II – SECA1401 1 1. FEEDBACK AMPLIFIER INTRODUCTION An ideal amplifier will provide a stable output which is in an amplified version of the input signal. But the gain and stability of practical amplifiers is not very good because of device parameter variation or due to changes in ambient temperature and nonlinearity of the device. This problem can be avoided by the technique of feedback wherein a portion of the output signal is feedback to the input and combined with the input signal to produce the desired output. The feedback can be either negative (degenerative) or positive (regenerative).In negative feedback a portion of the output signal is subtracted from the input signal and in positive feedback a portion of the output signal is added to the input signal to produce desired output. Negative feedback plays a very important role in almost all the amplifier stabilization of biasing circuits, it causes the location of the quiescent point to become stable. Thus it maintain a constant value of amplifier gain against temperature variation, supply voltage etc. The feedback may be classified into two types. Types of feedback (i) Positive feedback. When the feedback energy (voltage or current) is in phase with the input signal and thus aids it, it is called positive feedback. This is illustrated in Fig. 1.1. Both amplifier and feedback network introduce a phase shift of 180°. The result is a 360° phase shift around the loop, causing the feedback voltage Vf to be in phase with the input signal Vin.
