Current-mode continuous-time filters: two design approaches

Two different ways of implementing current-mode analog signal filtering are proposed. A practical comparison of filter structures using programmable current mirrors and single transistors as current integrators versus filters using an approach involving transconductors and current replica circuits is presented. Experimental results for a bandpass filter using the current mirror approach are presented and discussed.<>
