Abstract

A G-C 4th order bandpass filter with on-chip automatic frequency and Q-factor tuning is realized in 0.8 μm digital CMOS. The filter operates at nominal 21.4 MHz center frequency but can also be tuned to cover the frequency range from 15 to 30 MHz. It occupies 0.48 mm, and at 5 V supply it dissipates 15 mW, achieves 62 dB signal-to-noise ratio in the passband, -43 dB intermodulation distortion and a 3rd order intercept point of 24 dBm for a 3 Vpp input overdrive signal.
