ISBN 978-91-7501-614-6 TRITA-ICT/ES AVH 12:10 ISSN 1653-6363 ISRN KTH/ICT/ECS/AVH-12/10-SE Copyright © Liang Rong, December 2012 Contact: [email protected] Royal Institute of Technology (KTH), Sweden School of Information and Communication Technology Department of Electronic Systems Forum 120, Isafjordsgatan 39 SE-164 40 Kista, Stockholm Sweden Abstract The evolving wireless communication technology is aiming high data rate, high mobility, long distance and at the meantime, co-exist with various different standards. This developing trend requires a highly linear transceiver system and it causes the problem of low efficiency due to the large crest factor of signals. On the other hand, with process scaling, digital blocks are occupying more functions and chip area than before, to fully utilize the digital process low power advantage and save design cost, hardware reuse is preferable. The concept of Software Defined Radio (SDR) is raised to make the system more adaptable to multiple communication standards with minimal hardware resources. In this doctoral dissertation work, the software defined radio architecture especially the all-digital polar transmitter architecture is explored. System level comparison on different transmitter topologies is carried out in the first place. Direct conversion, out-phasing and polar transmitter topologies are compared. Based on the system level evaluation, a Lowpass Sigma Delta Modulation (LPSDM) digital polar transmitter is designed under 90nm CMOS process and packaged in QFN32. 19.3% peak efficiency and 11.4dBm output power is measured under single 1.0V supply. The constellation measurement achieved 5.08% for 3pi/8PSK modulation and 7.01% for QAM16 modulation output. The measurement on the packaged transmitter AM/AM and AM/PM also demonstrated the linearity and power efficiency performance under low voltage environment. This verified the possibility for a fully SDR solution in the future. As a specific application and genuine creation, the UHF RFID standard is mapped into digital polar transmitter architecture. System Royal Institute of Technology (KTH) Sweden, Ph.D. Thesis II ABSTRACT level simulation is performed and transient signal parameters are extracted. To prove the SDR possibility, the system is fully designed by VHDL language and downloaded into FPGA hardware with high speed serial port. The measured results confirm the possibility of the digital polar transmitter architecture potential in SDR system realization. Based on the design and verification of two different systems, the methodology for digital implementation of linear transmitter system is developed and the skill to carry out optimization and measurement is also possessed. In conclusion, the academic publication and verification proved the feasibility of digital polar transmitter application in linear system and point out the direction for a fully SDR realization.

Printed by LiU-Tryck, Linköping, Sweden 2017 To my mother, father, and uncle (mamoo), Abstract The market for wireless portable devices has grown significantly over the recent years. Wireless devices with ever-increased functionality require high rate data transmission and reduced costs. High data rate is achieved through communi- cation standards such as LTE and WLAN, which generate signals with high peak-to-average-power ratio (PAPR), hence requiring a power amplifier (PA) that can handle a large dynamic range signal. To keep the costs low, modern CMOS processes allow the integration of the digital, analog and radio functions on to a single chip. However, the design of PAs with large dynamic range and high efficiency is challenging due to the low voltage headroom. To prolong the battery life, the PAs have to be power-efficient as they consume a sizable percentage of the total power. For LTE and WLAN, traditional transmitters operate the PA at back-off power, below their peak efficiency, whereas pulse-width modulation (PWM) transmitters use the PA at their peak power, resulting in a higher efficiency.

  • Digital Polar Transmitter for Multi-Band OFDM Ultra-Wideband
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by ScholarBank@NUS DIGITAL POLAR TRANSMITTER FOR MULTI-BAND OFDM ULTRA-WIDEBAND LOKE WING FAI A THESIS SUBMITTED FOR THE DEGREE OF MASTER OF ENGINEERING DEPARTMENT OF ELECTRICAL & COMPUTER ENGINEERING NATIONAL UNIVERSITY OF SINGAPORE 2008 ABSTRACT Multi-Band Orthogonal Frequency Division Modulation (MB-OFDM) Ultra- Wideband (UWB) suffers from a large peak-to-average ratio (PAR). Systems with large PAR require the linear power amplifier (PA) to back off from its maximum output power to ensure that the peak of the power is within the linear range of operation, hence, resulting in poor efficiency. Although the problem of low power efficiency and high PAR may be solved by polar modulation, the performance of polar transmitter is often degraded by non-ideal implementations. This thesis studies the requirements for the envelope and phase signals in polar transmitter for UWB at system level. Results show that the bandwidth of the phase in the polar transmitter needs to be several times the bandwidth of in-phase (I) and quadrature phase (Q) in order to pass the Error Vector Magnitude (EVM) requirement in ECMA standard. On the other hand, the bandwidth of the amplitude does not need to have a bandwidth as large as the bandwidth of the phase – it needs to be only slightly larger than the bandwidth of I/Q. To take advantage of the advancement of deep-submicron semiconductor technology which favors more digital circuitries, a new digital polar transmitter (DPT) for MB- OFDM UWB is proposed.

  • A 2.4 Ghz Phase Modulator for a Wlan Ofdm Polar Transmitter in 0.18 Um Cmos
    A 2.4 GHZ PHASE MODULATOR FOR A WLAN OFDM POLAR TRANSMITTER IN 0.18 UM CMOS A Dissertation by SHOKOUFEH ARBABI Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE Chair of Committee, Kamran Entesari Committee Members, Sunil Khatri Samuel Palermo Ben Zoghi Head of Department, Chanan Singh December 2014 Major Subject: Electrical Engineering Copyright 2014 Shokoufeh Arbabi ABSTRACT This research focuses on the design and implementation of a digital active phase modulator path of a polar transmitter in the case of orthogonal frequency division multiplex WLAN application. The phase modulation path of the polar transmit- ter provides a constant envelope phase modulated signal to the Power amplifier (PA) , operating in nonlinear high efficient switching mode. The core design of the phase modulator is based on linear vector-sum phase shifting topology to differential quadrature input signals. The active phase shifter consists of a DAC that generates binary weighted currents for I and Q branches and differential signed adder that vector-sums the generated quadrature currents to generate the phase at the output.6 bits control the phase shifter, creating 64 states with the resolution of 5:625 ◦ for the whole 360 ◦. The linear (binary weighted) vector-sum technique generates a reduc- tion in the resultant amplitude that should be taken into consideration in case of nonlinear PA in polar transmission. On the other hand, the digital phase informa- tion is applied as the control bits to the phase shifter that determine the weightings and the signs of the I and Q vectors.

ABSTRACT The Class E power amplifier has very high drain efficiency under quasi-static conditions, and is a good candidate for Envelope Elimination and Restoration (EER) or other polar techniques. Unfortunately it has an unusual carrier frequency response, for which no analytic expression was known; this may have limited commercial use of the circuit. Two new steady state analyses are presented, which give the carrier frequency response in simple form, together with expressions for component values. Good agreement with measured data and existing numerical solutions is seen. Previous attempts at characterising the amplitude modulation (AM) behaviour of this circuit have assumed that it can be modelled as a first order low pass filter. It is shown that Class E AM can be modelled as an equivalent circuit, which behaves as a second order low pass filter.
