Abstract

A fifth-order Gm-C low-pass filter, which employs source degeneration linearization technique, used in analog frontend anti-aliasing is presented. This filter was simulated in the TSMC 0.18-μm CMOS process design kit (PDK) with 5-fF/μm2 MIM capacitors. This simulated filter features corner frequency of 20MHz, power consumption less than 4mW, supply voltage of 2V, THD of 1% at 260mVpp. The total area of this design is less than 0.2mm 2.
