Abstract :
A new design technique for switched current filters is presented. The basic element of the filter is a current mirror that employs MOS transistors and an operational amplifier. Programmability of the current mirror is obtained through MOSFET-only current dividers. User programmable analog functions in digital CMOS technology is the main envisaged application for the proposed technique
