Abstract :
An approach for the direct translation of conventional RC active filters into CMOS integratable structures is presented. This technique is based on the replacement of resistors by differential gain stages, and of op-amps by single ended gain stages. A high-frequency compensated CMOS universal filter derived using this method is shown and experimentally verified
