  • Capacitors Demystified: Practical Information on Capacitor Usage in EE133
    EE133–Winter 2004 Capacitors Demystified Capacitors Demystified: Practical information on capacitor usage in EE133 Why do I need to read this? Despite all we know about capacitors from previous exposure (including everyone’s favorite capacitor fact – ‘Well, I know the voltage across a capacitor cannot change instantaneously!’), there is a quite a bit about the (good) properties and (bad) non- idealities of these devices that effects the way they are actually used in RF circuits. So, with the practical predisposition of EE133, let’s take another look at our old friend… The Starting Line-up Like fine cheeses or candy bars, capacitors come in wide variety of sizes, shapes, and prices- and they can be made from a host of different materials (except for nougat). However, all of these characteristics are interrelated because, in classic Murphy fashion, a capacitor that ranks well in one or two of these properties is usually terrible in the other categories. The physical size and shape are only of marginal importance to us since the former is pretty much irrelevant at the size of our solder board and the latter is only for aesthetics (which is a foreign term to EE’s anyway). But, the composite material is an important factor in determining the behavior of the capacitor, so for the purpose of this class we will identify four major types (Refer to page 21 of “The Art of Electronics” by Horowitz & Hill for a more complete listing of capacitor families): Material/Comments Picture Ceramics (10 pF – 22µF): Inexpensive, but not good at high frequencies Tantalum (0.1µF – 500µF): Polarized, low inductance Electrolytic (0.1µF – 75µF): Polarized, not good at high frequencies (NOTE: longer lead is usually the positive terminal) Silver Mica (1 pF – 4.7 nF): Expensive with only small capacitive values, but great for RF 1 EE133–Winter 2004 Capacitors Demystified Some Commonly Asked Questions about Capacitors Resistors are color-coded.

  • Coupling for Power Line Communication: a Survey Luis Guilherme Da S
    JOURNAL OF COMMUNICATION AND INFORMATION SYSTEMS, VOL. 32, NO. 1, 2017. 8 Coupling for Power Line Communication: A Survey Luis Guilherme da S. Costa, Antonio Carlos M. de Queiroz, Bamidele Adebisi, Vinicius L. R. da Costa, and Moises V. Ribeiro Abstract—The advent of power line communication (PLC) electric power cables. These power cables could be alternating for smart grids, vehicular communications, internet of things current (AC) or direct current (DC) power lines and the signals and data network access has recently gained ample interest in of PLC transceivers are subsequently coupled to them via a industry and academia. Due to the characteristics of electric power grids and regulatory constraints, the effectiveness of coupling circuit. In the case of power lines used to transmit coupling between the power line and PLC transceivers has AC power, the coupling circuit has also to filter out the AC become a very important issue. Coupling devices used to inject or mains signal. On the other hand, the coupling circuit simply extract data communication signals into or from power lines are has to block the DC mains voltage of the DC electric power very important components of a PLC system. There is, however, grids. an obvious gap in the literature for a detailed review of existing PLC couplers. In this paper, we present a comprehensive review During the late 1970s and early 1980s, new investigations of couplers, which are required for narrowband and broadband to characterize electric power grids as a medium for data PLC transceivers. Prevailing issues that protract the design of communication showed a higher potential in the range of couplers and consequently subtended the inventions of different frequencies between 5 kHz and 500 kHz [2].

  • Beam, Coupling Impedance
    Beam Impedance, Coupling Impedance, and Measurements using the Wire Technique John Staples, LBNL Beam, Coupling Impedance When a particle beam of current I travels through a structure, it may give up some of its energy to that structure, reducing its energy. The energy loss may be expressed as a voltage V, and the beam impedance Zb of the structure itself may be expressed as V loss Z b = I beam The structure may be a monitor device, where a signal V is generated by the beam and detected. In this case, we can define a coupling impedance Zp for the structure V monitor Z p = I beam In general, these are not the same, and each depends on the details of the structure itself. Stripline Monitor A beam bunch, as it travels down a pipe, induces images charges on the interior surface of the pipe. If the pipe is smooth and lossless, these charges do not affect the beam. An irregular beam pipe, however, will interact with the beam, as fields are induced in the beam pipe by the beam. The fields of a relativistic beam are concentrated along the direction of motion. One very useful type of monitor is the stripline monitor, which responds to the image charges. An electrode or electrodes are mounted in the beam pipe. Each end of the electrode is brought out and connected to a load. The electrode subtends and angle q. The geometry of the stripline resembles that of a microstrip, which has a characteristic surge impedance. The propagation velocity of an impulse along the stripline is assumed to be the speed of light c.

  • Capacitors Capacitors
    Capacitors There seems to be a lot of hype and mystery concerning the sound of capacitors, the quality of capacitors and what capacitors actually do in a circuit. There are many types of capacitors including ceramic, polyester, polypropylene, polycarbonate silver mica, tantalum and electrolytic. Each has its own area of “expertise”. One type of capacitor will perform well in a particular application and perform poorly in another. A capacitor is simply two metal plates separated by a dielectric. An electrical charge is stored between these two plates. The plates and dielectric can be made form several different types of material. The closer the plates are, the higher the capacitance and the larger the area of the plates, the larger the capacitance. The dielectric material affects the capacitance as well. Here is some brief information about the particular types. Note: The unit of capacitance is the Farad. It is a very large unit and so we use the following to express capacitance Microfarad is one millionth of a farad. Picofarad is one millionth of a microfarad So 0.001mfd is equal to 1000 picofarad (pF) The above diagram shows a simple representation of a capacitor. The capacitor is shown in RED . In parallel with the plates of the capacitor is a resistance, InsInsIns-Ins ---ResRes of the insulation. Teflon has the highest resistance with polystyrene, polypropylene and polycarbonate coming in second. Third is polyester and then the ceramics COG, Z5U and XR7 with tantalum and aluminium last. Dap is the Dielectric Absorption. All capacitors when charged to a particular voltage and then the leads are shorted, will recover some of their charge after the short is removed.

Email: [email protected] Received February 14th, 2012; revised March 12th, 2012; accepted March 24th, 2012 ABSTRACT This paper deals with the design of bidirectional coupler for broadband power line communication and the impedance matching technique with the power line. This coupler can be used for both transmitting and receiving the data, acting as transceiver. The impedance mismatching problem is also solved here using line trap circuit. The coupler circuit is capa- ble of transmitting or receiving modulated signals with carrier frequency of 15 MHz which can be used for domestic as well as distribution power networks. Laboratory prototype tested using power line network consists of electrical house- hold appliances and results show that the circuit is able to facilitate bidirectional band pass transmission.
