Abstract :
A new approach to design low-voltage SC filters is presented. It is based on a simple structure of clock booster and on an SC integrator which uses a single-input transconductance amplifier instead of the traditional differential transconductance amplifier. To validate the approach a low-pass 4th-order elliptic filter with a 1.2 μm CMOS process and 1.5 V power supply is designed
