A class of MOSFET-C multifunction filters

In this paper, a set of current-mode MOSFET-C multifunction filters are presented. Since MOS transistors operating in saturation region are used instead of the passive resistors, key filter parameters are all electronically controllable. The main properties of a total of eight different multifunction filters are catalogued in tabular form. The proposed circuits exhibit attractive features such as circuit simplicity and reduced chip area compared to the classical analog filters that require active elements including large number of transistors. All the filters are simulated in spectre simulation software in Cadence design environment using 90 nm UMC CMOS process parameters.
