Abstract
A new technique to achieve switched current filters is presented. The basic elements of the filters are operational amplifiers, switches, MOS transistors and grounded capacitors. The use of MOSFET-only current dividers allows digitally programming of the coefficients of the filter transfer function. User programmable analog filtering in digital CMOS technology and, particularly, in sea-of-gates is the main envisaged application of the proposed technique
