AC coupled multistage high gain operational amplifier

Year	Description
2002	Invention patented by Iuri Mehr, Lawrence A. Singer, and Wenhua Yang on May 7th, 2002. Abstract: An a.c. coupled multistage high gain operational amplifier includes at least two gain stages, each having an input and an output; an a.c. coupling level shifting capacitance interconnecting the output of a first stage to the input of a second stage; and a charging circuit interconnecting with the a.c. coupling level shifting capacitance and the input of the second stage to charge the a.c. coupling level shifting capacitance in a track phase and to connect the a.c. coupling capacitance to the input of the second stage during a hold phase for dissociating the bias voltages of the stages.
