发明名称
摘要 <p>The variable impedance circuit comprising the invention provides a circuit having an impedance which varies in response to an input signal. The invention utilizes a control circuit which samples the load current and compares it to the demand signal to generate a control signal. The control signal is coupled to a load driver circuit to cause the required current to flow through this circuit. The load driver circuit and one or more substantially identical load circuits are series coupled to form a variable impedance circuit having the desired voltage and current capability.</p>
