A differential value detecting circuit made by LTC1043

As the picture a and b show, this is a differential value detecting circuit made by LTC1043, in which the differential terminal is changed into single terminal output terminal. Picture20 (a) shows the basic detecting amplifier with speeding up capacitor mode. The sample C1 is connected to differential input signal terminal and uses differential input voltage Ui to charge. And LTC1043 is used to handoff and connect C1 to C2 while the electric charge of C1 is transferred to Q. Due to the repeating frequency of hundreds to some dozens of thousands, voltage of the differential input signals changes to signal input voltage of A1. The repeating frequency is decided by LTC1043 and capacity of C3(EXT capacitor ).
