Abstract

This paper describes the gm-C filter design with the proposed wide-range transconductance amplifier. The transconductance amplifier includes the auxiliary positive feedback differential pair to enhance the operating range with small variation of gm value. The 100MHz 7th-order 0.05° equiripple linear-phase lowpass filter is designed in a 0.35-μm CMOS technology. The 3-dB frequency can be finely programmed and maintained through on-chip tuning PLL. The filter operates at the single power supply voltage of 3.3V.
