摘要: The present invention provides a fully differential telescopic operational amplifier having switch capacitor common mode feedback (CMFB) circuit portion. switched CMFB portion has current mirror for mirroring from first transistor to second transistor. and transistors have gates which are coupled via transmission gate switch. Drains of each the respectively pair transistors, connected receive voltage drains scaled with respect other such that source is substantially equal
