【 摘 要 】

References(3)Class-AB circuits, which are able to deal with currents which are orders of magnitude larger than their quiescent current, are good candidates for low-power analog design. This paper presents a new, simple, class-AB current-mirror, based on the Flipped Voltage Follower [1]. In the authors knowledge this is the first class-AB current-mirror which operates with a supply voltage smaller than two transistor threshold voltages without an additional clock signal or voltage doubler. Experimental results are provided which show proper operation at 1.5V in a 0.5µm standard CMOS technology.
