Title: Differential amplifier
Inventor: SAITOU SEIICHI
IPC: H03F3/45
Filed: 1982-01-22
Abstract: PURPOSE:To delete the drift component and to obtain an output of high accuracy with a simple constitution, by providing a switch at the input of an amplifier to perform the switching between two signals and sampling and holding one of the two signals to deliver the differential between the output of the sampled and held signal and the other signal. CONSTITUTION:The 1st switch SW1 is set at the input side of an amplifier 4 which amplfies analog input signals V1 and V2, and the signal V2 is amplified. Then the output of amplfication is stored in a capacitor C via the 2nd switch SW2 of a sample holding circuit 8. The switches SW1 and SW2 are switched to amplify the signal V1 by the amplifier 4. The amplfied signal V1 is then supplied to an amplifier 7, and at the same time the output held at the capacitor C is supplied. Then the differential between the signals V1 and V2 is delivered to the output of the amplifier 7, and the drift component is deleted. Thus an output signal V0 of high accuracy is delivered.
