Small-Signal Characteristics of the Diode-Stabilized Linear Integrated Devices

The small-signal characteristics and the frequency response of the diode-stabilized linear integrated devices (circuits) are examined. The built-in feedback property is explained. It is found that the circuit provides low input impedance, high output impedance, and small internal feedback. The frequency response of the circuit with the bias-diode is superior to that without the bias-diode. The current gain of the circuit can be controlled by appropriate design of active or passive elements. The experimental results using discrete components agree with the analysis.
