Patent JP-H0340300-A (JP)
Title: Sample-and-hold circuit
Inventor: SEIKE MAMORU
IPC: G11C27/00
Filed: 1989-07-06
Abstract: PURPOSE:To simplify configuration and to reduce an offset voltage by canceling a spike electric charge, which is generated when an analog switch is changed over from ON to OFF, with a compensating circuit composed of a complementary MOS Tr. CONSTITUTION:A pMOS Tr 3' and an nMOS Tr 4' constitute the electric charge compensating circuit 8 of a spike voltage. When the potential of a clock input terminal A is changed from 'H' to 'L', namely, when an analog switch 7 is changed from ON to OFF, the spike electric charge to inject from a gate electrode to source and drain is generated. However, the charge is canceled by an electric charge compensating circuit 8 and the offset voltage by the analog switch 7 is not added to the electric charge to be charged in a capacitor 6. Thus, a sample-and-hold circuit, for which the offset voltage is reduced, can be obtained.
