Title: Dc bias fluctuation eliminating circuit
Inventor: KARAKI TAKEHISA
IPC: H03K17/14
Filed: 1989-03-10
Abstract: PURPOSE:To eliminate DC bias fluctuation caused due to time change of condition by making signals inputted to two emitter followers from a signal source such as an optical sensor equal to each other in terms of DC. CONSTITUTION:An output of an optical sensor 11 is inputted to emitter follower circuits 12, 13, each output is inputted to two input terminals of a differential amplifier 14 of the next stage, the difference signal is amplified and outputted to an output terminal T3. Since the resistance values of resistors 12-2, 12-3 and resistors 13-2, 13-3 are equal to each other in terms of Dc, the voltage at the output terminal T1 and the voltage at an output terminal T2 are made equal. The DC output voltage is cancelled together by the differential amplifier 14. On the other hand, since the output terminal T2 of the emitter follower circuit 13 connects to ground by a static capacitance 16, the AC signal of an optical sensor 11 is outputted at the output terminal T1 of the emitter follower circuit 12, it is amplified by the differential amplifier 14 and outputted from an output terminal T3. Thus, the effect due to DC bias fluctuation is eliminated.

Abstract: PROBLEM TO BE SOLVED: To improve an S/N by making an output signal value read from an amplifier transistor to a signal line equivalent to a difference between an input signal value when a detection signal is present in the input of the amplifier transistor and the input signal value when the detection signal is not present. SOLUTION: When a bias electric charge injection gate 15 is turned ON and bias electric charges are injected from the channel of the amplifier transistor 12 through a bias electric charge injection terminal 15 set to a low potential to a signal amplifier capacitor 14, excessive bias electric charges are made to flow out from the signal amplifier capacitor 14 to an output terminal 16 through the channel of the amplifier transistor 12 and the potential of the signal amplifier capacitor 14 becomes equal to the potential of the amplifier transistor 12.  When a reset gate 13 is turned ON and the potential of a photodiode 11 is reset to a reset potential, the channel potential of the amplifier transistor 12 rises and the electric charges stored in the signal amplifier capacitor 14 are read through the channel of the amplifier transistor 12 to the output terminal 16 for the change of the potential of the amplifier transistor 12 and turned to signal electric charges.
