Title: Sample and hold circuit
Inventor: KATOU KIKUO
IPC: G11C27/02
Filed: 1984-05-25
Abstract: PURPOSE:To maintain an output dynamic range and to perform low-voltage operation by switching bias constant current source having differential constitution with a sampling pulse and turning on and off a voltage follower circuit. CONSTITUTION:A bias circuit 30 for switching outputs a low-level voltage in a period in which sampling pulses are inputted to a terminal 23 and the low-level voltage is applied to gates of transistors (TR) of the voltage follower circuit 36, which turns off. Therefore, a voltage follower output voltage obtained by regenerating an input signal at a terminal 6 appears at a terminal 14 of the circuit 36 and is charged in a holding capacitor C26. Then, the circuit 30 outputs a high- level voltage in a holding period to turn on the TRs 33 and 34, and a differential couple of TRs 15 and 17 turn off; and there is neither a charging nor a discharging pulse arriving, and the C26 holds the charges in the sampling period.
