Abstract: A sample and hold circuit using a first and second operational transconductance amplifier with a voltage storing device connected in circuit between the first and second amplifiers. A sample of the amplitude level of an input signal is stored in the storage device at predetermined times when the first amplifier is rendered operative. The sampled level is provided at the circuit output terminal at other predetermined times when the second amplifier is rendered operative.
