Abstract: A bidirectional, transconductance, DC amplifier exhibiting a compliance voltage exceeding either of the DC power supply voltages nearly double the compliance voltage of conventional circuits. The circuit uses a differential input operational amplifier. A voltage divider has its first resistor connected between the amplifier input and the noninverting input of the operational amplifier. The second resistor of the voltage divider is connected between the noninverting input and a common ground. A third resistor is connected between the amplifier input and the inverting input of the operational amplifier. A feedback circuit branch is connected between the inverting input and the output of the operational amplifier and includes a pair of output terminals for connecting the load in series in the feedback circuit branch.
