Title: Differential amplifier circuit
Inventor: OTSUJI YUICHI
IPC: H03F3/34
Filed: 1991-08-31
Abstract: PURPOSE:To provide the differential amplifier circuit capable of preventing the malfunction due to diffusion layer leakage current. CONSTITUTION:In the case of connecting a P-channel MOS type electric field effect transistor(PchM0SFET)Q3 for cutting the power supply between an output terminal OUT and a power supply VDD, the diffusion layer leakage current flows from the first diffusion layer which makes the drain area to the output terminal OUT even when the PchM0SFETQ3 is turned off at the normal operation. Then, a PchMOSFETQ4 having the same characteristic as the PchM0 SFETQ3 is connected between a nodal point 1 and the power supply VDD. Thus, the diffusion layer leakage current flows from the second diffusion layer which makes the drain area of the PchMOSFETQ4 to the nodal point 1, the potential of the nodal point 1 and the potential of the output terminal OUT become equal. Therefore, the generation of the input offset can be prevented, resulting in preventing the malfunction due to the diffusion layer leakage current.
