Abstract
An automatic control circuit for an electrosurgical generator is herein disclosed. The automatic control circuit includes voltage and current sensing circuits, a processing circuit, a dosage calculating circuit, and control circuit. Samples of the voltage and current outputs are supplied to the processing circuit and the dosage calculating circuit to generate a dosage output signal. The dosage output signal is compared to a reference signal to generate a feedback signal that controls a drive circuit.
