ABSTRACT:
An impedance synthesizer includes an amplifier with selectable gain and a reference capacitor, resistor, or inductor for providing a plurality of synthesized impedance values. The voltage gain of the amplifier is controlled by a programmable multiplying digital-to-analog converter which allows the selection of a myriad of desired synthesized impedances with high precision and accuracy.
