A transformer-based receiver designed in 45nm CMOS that meets WCDMA, GSM, GPRS, and EDGE system requirements is presented. The receiver requires no interstage SAW filters and consumes 20mA from 1.4V. The use of a transformer at the LNA output helps a

We present a low-complexity digital baseband detector for GSM applications for functional RF BIST of the receiver section of a complex transceiver SoC implemented in 90-nm digital CMOS process. The detector can be used as a pass/fail criterion during

The RF transceiver is built on the Digital RF Processor (DRP) technology. The ADPLL-based transmitter uses a polar architecture with all-digital PM-FM and AM paths. The receiver uses a discrete-time architecture in which the RF signal is directly sam

We present mathematical analysis to prove that LO leakage at the input of RF circuits in the presence of finite IIP3 results in asymmetry in DC offsets and IIP2 between in-phase and quadrature channels in a wireless receiver. The asymmetry in IIP2 ca

We present a low-area and low-power implementation of the first antialiasing and decimation filter following an ultra-high speed 1-bit /spl Sigma//spl Delta/ A/D converter operating between 430-600Msps in a wireless transceiver. This filter is implem
