Abstract :
We present a programmable fourth-order Butterworth continuous-time filter with a bandwidth programmable from 60-350 MHz, implemented in a 0.25µm digital CMOS process. It is intended for communication and mass storage applications. The filter has a dynamic range of 54dB, dissipates 70mW from a 3.3 volt supply and occupies an area of 0.15mm2. Suitably biased accumulation MOS capacitors are used as integrating elements.
