TL;DR: This paper describes the design and performance of a 90 nm CMOS SAW-less receiver with DigRF interface that supports 10 WCDMA bands and 4 GSM bands and results in current drain and die area savings as well as improved noise.

TL;DR: The RF transceiver is integrated with the baseband signal processing and associated passives in a 165-pad package, resulting in the first tri-band 3G radio transceiver with a digital interface which requires no external components.

TL;DR: In this paper, a high performance radio frequency receiver includes a low-noise amplifier with large binary and stepped gain control range, controlled impedance, and enhanced blocker immunity, for amplifying and converting a radio frequency signal to a current; a pulse generator for generating in-phase and quadrature pulses; a crossover correction circuit and pulse shaper for controlling a crossover threshold of the pulses and interaction between inphase and Quadrature mixers; and a double balanced mixer for combining the RF signal with the pulses to generate an intermediate frequency or baseband zero intermediate frequency current-mode signal

TL;DR: In this paper, a high performance radio frequency receiver includes an isolated transconductance amplifier with large binary and stepped gain control range, controlled impedance, and enhanced blocker immunity, for amplifying and converting a radio frequency signal to multiple electrically isolated currents.

TL;DR: In this paper, the digital signal processor controls the digital-to-analog converter to output bias voltages for the gate of at least one of the CMOS devices of the mixer to compensate for imbalance in the differential output of the mixers.
