Abstract
Switched-current (SI) is a current-mode analog sampled-data signal pro cessing technique realizable in standard digital CMOS technologies. In this paper, new switched-current (SI) mirrors using OTAs (operational transconductance amplifiers) are proposed. These circuits are less se nsitive to clock-feedthrough noise than conventional SI mirrors by vir tue of linear I-V/V-I transformations. In addition, the current gain o f the proposed mirror is electronically tunable. Not only inverting mi rrors but also noninverting mirrors can be realized by this method.
