Abstract
Based on the theory of switched capacitor (SC) filters using voltage invertor switches (VIS) a third order lowpass filter has been designed and integrated in a standard CMOS metal gate technology. The filter uses a bottom plate stray-insensitive VIS and requires only unity gain buffers. Performance parameters of an integrated version are: cutoff frequency 170 kHz, dynamic range 70 dB, and power dissipation 12 mW.
