Abstract :
We present a fifth order Chebyshev singly-terminated ladder filter with a band-edge frequency programmable from 70-500 MHz implemented in a 0.35 ¿m CMOS process. It uses constant-capacitance scaled Gm-C integrators, and features a technique for compensation of MOS nonquasistatic effects. Also incorporated in the design is a robust fixed-transconductance bias circuit. The filter has a dynamic range of 52 dB and consumes 100mW from a 3.3V supply.
