ABSTRACT:
In a sample-and-hold circuit having two voltage amplifiers connected in series via a switch, which is arranged to perform on-off operations in accordance with a control signal, the noninverting input terminal of the second voltage amplifier of output side is grounded so that the switch can be used at an imaginal short point of the second voltage amplifier. As a result, a semiconductor switch having a simple construction may be used as the switch, while a switch drive circuit may also be simple. Furthermore, since great negative feedback effect can be attained during sampling mode, the sample-and-hold circuit is capable of operating with high accuracy. Additional switches may be employed for improving feedthrough characteristics, while means for preventing undesirable oscillation may be provided if necessary.
