ISSCC 2017 Session 18 Wireless
A 1.7-to-2.2GHz Full-Duplex Transceiver System with >50dB Self-Interference Cancellation over 42MHz Bandwidth
Tong Zhang, Ali Najafi, Chenxin Su, Jacques C. Rudell
Full-duplex (FD) radio communication potentially doubles the spectral efficiency in the densely occupied RF spectrum (100MHz to 5GHz). However, significant challenges remain, particularly the presence of a strong transmi

Voltage-Scalable Frequency-Independent Quasi-Resonant Clocking Implementation of a 0.7-to-1.2V DVFS System
Fahim U. Rahman, Visvesh S. Sathe
Clock power remains a substantial contributor to power dissipation, from ultralow-power to high-performance systems [1, 2, 3]. Recently, resonant clocking has been shown to achieve power reduction in clock distribution n

A ±3ppm 1.1mW FBAR Frequency Reference with 750MHz Output and 750mV Supply
Kannan A. Sankaragomathi1, Jabeom Koo1, Richard Ruby2, Brian P. Otis1
Multiple emerging wireless applications (body-worn devices and IoT, for example) will demand previously impossible thin-film form factors and low system cost. One key enabling technology for this paradigm is a new class
ISSCC 2014 Session 21 Clocking & PLLs
A 1.8mW PLL-Free Channelized 2.4GHz ZigBee Receiver Utilizing Fixed-LO TemperatureCompensated FBAR Resonator
Keping Wang1, Jabeom Koo1, Richard Ruby2, Brian Otis1
Avago Technologies, San Jose, CA 1 feed forward the RF signal into M4 and M6 to reduce the differential signal imbalance. Simulated results show that the gain and phase imbalance of the proposed LNA are improved by 5.6dB
ISSCC 2013 Session 25 Wireless
A 1.6mW 300mV-Supply 2.4GHz Receiver with -94dBm Sensitivity for Energy-Harvesting Applications
Fan Zhang1, Keping Wang1, Jabeom Koo1, Yasunori Miyahara2, Brian Otis1
9.3 shows the schematic of the IF-chain. Due to the severe headroom limitation, we used two single-ended self-biased inverters instead of OTAs as IF amplifiers. Compared to a conventional common-source stage, this curren

A 120µW MICS/ISM-Band FSK Receiver with a 44µW Low-Power Mode Based on Injection-Locking and 9x Frequency Multiplication
Jagdish Pandey, Jianlei Shi, Brian Otis
For true low-power peer-to-peer wireless links for sensing, link symmetry must be maintained unlike in [1,2] where the burden is shifted to the receiver. In addition, the transceiver power dissipation and performance sho

A Switched-Capacitor Power Amplifier for EER/Polar Transmitters
Sang-Min Yoo, Jeffrey S. Walling, Eum Chan Woo, David J. Allstot
Wireless high-speed communication standards such as WiFi, WiMax and LTE use spectrally-efficient OFDM modulation that encodes signal information in both amplitude and phase. Use of this non-constant envelope modulation r
