Dynamically power-optimized channel-select filter for zero-IF GSM

A 1.2 V channel-select filter is implemented in a 0.18 /spl mu/m digital CMOS process for a zero-IF GSM system. The filter includes a coarse AGC system with dynamic impedance scaling and dynamic biasing to optimize power consumption, which is scaled down in 5 steps from 2.6 mW to 0.45 mW per channel without introducing transients due to the changes. The area per channel is 1.2 mm/sup 2/.
