Abstract

PURPOSE: To secure holding the output voltage under the non-input state at the less voltage (earth side) for the sample holding circuit featuring a high responsibility plus the reduced holding error and temperature dependence.
CONSTITUTION: Sampled signal 17 is applied to the input terminal of the sample switch consisting of Tr28 via the first complementary connection step comprising transistors Tr35 and 36, Tr37 with the base and the collector connected together and emitter follower Tr42 each, and also applied to the above mentioned sample switch circuit via the second complementary connection step comprising Tr40 and 41. Holding capacitor 31 is connected between the earth and the output terminal of the sample switch, and the output is drawn out via the third complementary connection step consisting of Tr45 and 46, Tr48, with the base and the collector connected together and emitter follower Tr49 each.
