The design and fabrication of a high bandwidth 3rd order analogue elliptic low-pass wave filter is described. The filter was realised using switched-current techniques and implemented on a standard digital 0.6?m CMOS process. The filter exhibits an elliptic response and achieves a bandwidth of 250kHz which is significantly higher than a previously reported fabricated switched-current wave filter.
