SAMPLE HOLD CIRCUIT, INTEGRATED CIRCUIT DEVICE, ELECTRO-OPTIC DEVICE, AND ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a sample hold circuit which can prevent the deterioration of characteristics of the circuit while reducing a circuit scale.;SOLUTION: A sample hold circuit comprises an operational amplifier OP1, a switch element SS for sampling, a capacitor for sampling, a switch element for feedback, and a switch element SA for flip-around. Sampling control lines LSP and LSN which supply sampling control signals for controlling the on/off-turning of the switch element SS for sampling are wired along the second direction D2 in the third direction D1 of a summing node line LNEG, and flip-around control lines LAP and LAN which supply flip-around control signals for controlling the on/off-turning of the switch element SA for flip-around are wired along the second direction D2 in the first direction D3 of a summing node line LNEG.;COPYRIGHT: (C)2009,JPO&INPIT
