摘要：
A novel differential current-mode integrator (CMI) for voltage-controllable low frequency continuous-time filters is presented. An example fifth-order lowpass filter using the proposed CMI and on-chip capacitors was implemented in an AMI 1.2 mum CMOS process, and it achieved -3 dB cutoff frequencies ranging from 160 Hz to 5.6 kHz, by changing a single control voltage.
