In this paper, the design and performance of a rail-to-rail low-voltage CMOS fifth-order elliptic low-pass GM-C filter for baseband mobile communication are presented. The operational transconductance amplifier (OTA) used in this filter is a low-voltage rail-to-rail voltage-to-current converter (V-I converter). In this V-I converter, an N-type V-I converter cell is connected in parallel with its counterpart, a P-type V-I converter cell, to achieve common-mode (CM) rail-to-rail operation. Two maximum-current selecting circuits and an output current subtraction circuit are utilized to generate constant-g m output currents for this OTA. This fifth-order elliptic low-pass GM-C filter operates at a supply voltage of 3 V and has a cutoff frequency of 280 to 405 KHz. It provides up to 700 mV pp output with 1% total harmonic distortion (THD), dissipates 2.48 mW at V cm - 1.5 V, and occupies 1.62 mm 2 in a 1.2-μm CMOS technology. © 1997 IEEE.
