Abstract :
A second order Gm-C filter designed in 1 μm MOS technology is presented. The main characteristics of the filter are high linearity and low power operation at 5 V supply. This circuit uses MOS gate capacitance for the filter. Circuit performance shows a THD of 55 dB for 1 volt (pk-pk differential) at 1 MHz. The area of the filter is 320 sq. mils. and its power dissipation is 18 mW
