Sample and hold circuitEnhanced feedback voltage of common mode feedback (CMFB) circuit is designed in this work for CMOS data sampling application using 0.18-渭m Silterra process technology. The double error detecting point circuit is employed to associate with the feedback point in order to ...
A continuous-time common-mode feedback circuit (CMFB)is presented.A two-stage high-gain architec-ture is used to minimize the offset of the common-mode voltage.A special compensation scheme enables this cir-cuit to be used in high-impedance current-mode systems without a stability problem....
