ABSTRACT:
A voltage source having a current feedback control loop for enhanced source impedance control of the output of the voltage source. Current feedback is used for a voltage-source amplifier wherein the source impedance is increased/decreased and/or reshaped by the voltage source amplifier's closed-loop gain and the additional current feedback. In particular, the enhanced source impedance control is accomplished through feedback of the output current of the voltage source to an analog error amplifier at an input to the voltage control loop. The output impedance Z.sub.desired is then adjusted in accordance with the equation Z.sub.desired =Z.sub.inv1 {1+G(s) H(s)}, where G(s) is the voltage source amplifier's closed-loop transfer function, H(s) is the transfer function of the output current feedback circuit and Z.sub.inv1 is the original source impedance of the voltage controlled voltage amplifier. Thus, once G(s) is defined, H(s) may be defined simply as the combined impedance of the output current feedback circuit. Impedance of this output current feedback circuit may then be altered until the source impedance of the circuit causes the voltage generating circuit to provide an output impedance which corresponds to the desired output impedance.
