An approach to the design of low-voltage SC filters

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 4/sup...

Zusammenfassung: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 4/sup th/-order elliptic filter with a 1.2 /spl mu/m CMOS process and 1.5 V power supply is designed.
