Abstract

An original active resistor circuit is presented in this paper. The main advantages of the new proposed implementation are the improved linearity, the small area consumption and the improved frequency response. The frequency response of the circuit is very good as a result of operating all MOS transistors in the saturation region. The circuit is implemented in 0.35 mum CMOS technology, the SPICE simulation confirming the theoretical estimated results and showing a linearity error under a percent for an extended input range and a small value of the supply voltage
