Abstract
A fourteenth-order CMOS transconductance-C (Gm-C) bandpass filter with on-chip automatic frequency tuning is described. By using highly linear Gm-C integrators, the filter achieves 75 dB dynamic range over 700 kHz noise bandwidth. The measured intermodulation distortion (IM3) @ 600 kHz for a 4 Vpp input signal is only -61 dB. On-chip automatic frequency tuning provides more than 300% center frequency range (i.e., 165-505 kHz) of the filter with ±1% frequency accuracy. The 0.7-μm CMOS filter measures 4.8 mm 2 and consumes 70 mW from a single 5 V power supply
