Abstract
A dynamic load circuit constructed so that the current shunted thereby is high at low voltages and low at high voltages. The impedance of the dynamic load circuit is negative over a portion of its operating range so that current will decrease with increasing voltage over that range. The foregoing is accomplished by the provision of a two-stage inverting direct current amplifier with a low impedance load and a selected offset voltage.
