Abstract

A prototype 1-6GHz multi-band sampled sliding-IF receiver with discrete-time channel select filtering in a 90nm low resistivity substrate, strained-Si digital CMOS process is presented. The core receiver has an inductor-less wideband LNA front-end, a sampled mixer, and a combination of programmable poly-phase FIR and IIR filter for baseband filtering. The receiver achieves a noise figure (NF) of <13.5dB and IIP3 of >-19dBm for bands between 1-6GHz. The receiver when used in a system with an external tuned LNA (2.5dB NF) on the front end module achieves NF of <7dB, and IIP3 of >-34dBm for the WiFi bands. The die area for the entire receiver is 0.8mm² and consumes 89mW
