Direct current correction circuit for charge transfer element
专利汇可以提供Direct current correction circuit for charge transfer element专利检索，专利查询，专利分析的服务。并且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 C
o is connected to the base of npn- type transistor Q
1 ', the collector of this transistor is to the power supply terminal 4 and the emitter is connected to the base of npn-type transistor Q
1 ". Next, the collector of transistor Q
1 " is connected to the power supply terminal 4 and the resistor R
1 ' is connected between the base and emitter, and the emitter is grounded via the resistor R
1 ". Further, the hot end of the capacitors C
2 , C
4 ...C
2n is similarly constituted. In this circuitry, when the value of R is selected so that the base current of transistors Q
1 , Q
1 ' is equal each other, the base current of transistor Q
1 is cancelled resulting in eliminating the DC voltage variation due to the base current with a simple constitution.
