Abstract

The paper discusses the synthesis of switched-current alters from continuous-time prototypes by the simulation of components, particularly capacitors and transconductors in OTA-C filters. The obtained structures implement discrete-time versions of the nodal equations of the prototype circuit using Euler or bilinear transformations over the circuit elements. All the proposed structures work with doubled effective sampling rate, do not use current-conducting switches, and are operated with a two-phases, non-overlapping clock system
