摘要：

Switched-current (SI) circuits represent a current-mode analog sampled-data signal processing technique realizable in standard digital CMOS technologies. In contrast to the switched-capacitor (SC) approach where ratios of linear capacitances determine time constants, SI circuit time constants depend on MOSFET aspect (W/L) ratios. Design issues comparing the implementation and performance of the SI technique to the ubiquitous SC technique are presented in this paper.
