Abstract
A design approach for low-voltage SC filters to be implemented in standard CMOS processes is presented. It is based on simple building blocks which are a clock booster and an SC integrator which uses a single-input amplifier instead of the traditional differential-input amplifier. To validate the proposed approach, a fourth-order elliptic SC low-pass filter was designed using a 1.2 μm CMOS process and 1.5 V power supply. The measured frequency response accurately agrees with the simulated one in which an infinite-gain amplifier was considered. When the power supply is set to 1.5 V, the filter has a power consumption of 400 μW and occupies a silicon area of 0.8 mm2
