Abstract

PURPOSE: To eliminate the DC potential variation due to base current with a simple constitution, by connecting the current source corresponding to the base current up to the prestage between the stages of charge transfer elements consisting of bipolar transistors.
CONSTITUTION: The hot end of the capacitor Co is connected to the base of npn- type transistor Q1', the collector of this transistor is to the power supply terminal 4 and the emitter is connected to the base of npn-type transistor Q1". Next, the collector of transistor Q1" is connected to the power supply terminal 4 and the resistor R1' is connected between the base and emitter, and the emitter is grounded via the resistor R1". Further, the hot end of the capacitors C2, C4...C2n is similarly constituted. In this circuitry, when the value of R is selected so that the base current of transistors Q1, Q1' is equal each other, the base current of transistor Q1 is cancelled resulting in eliminating the DC voltage variation due to the base current with a simple constitution.
