Suitable for positive input voltages. Negative feedback is applied to opamp through diode-connected transistor, with additional diode D protecting transistor from excessive inverse voltage caused by wrong input polarity. For negative inputs, reverse transistor and diode connections. Article gives design equations and application procedures.-G. B. Clayton, Experiments with Operational Amplifiers, Wireless World, Jan. 1973, p 33-35.
