The design and fabrication of a high bandwidth third-order analogue elliptic lowpass wave filter is described. The filter was realised using switched-current techniques and implemented on a standard digital 0.6 /spl mu/m CMOS process. The filter exhibits an elliptic response and achieves a bandwidth of 250 kHz, which is significantly higher than a previously reported fabricated switched-current wave filter.
