摘要：

A fully integrated low-distortion balanced continuous-time filter fabricated in 5-V 1.6-mum CMOS is presented. Active RC structures are used in a leapfrog topology, with time constants set by integrated passive resistors and capacitors. Accurate tuning is achieved by selection of capacitor elements under the control of a new calibrator circuit. With a 2-V(rms) differential input and output, the filter achieves -94-dB THD, and 95-dB signal-to-noise ratio. Tuning accuracy is maintained to within +/-5% of nominal over the commercial temperature range.
