Abstract
The Microcap circuit-analysis package was used to study a measuring circuit when a step voltage is applied to a dielectric specimen in series with the circuit and an operational amplifier is employed to provide an output suitable for driving a recording device. The authors investigated the effects of connecting an operational amplifier into the circuit in two different modes: the voltage-follower mode and the current-voltage converter mode. The treatment of the offset voltage, bias current, and offset current is described. Results are given for the AD515L operational amplifier and the AD310/311 operational amplifier. The minimum acceptable amplifier performance is discussed.<>
