Abstract
Methods and apparatuses are provided for neutral drive feedback loop compensation of detected electrosurgical unit signals. An apparatus includes an electrosurgery unit (ESU) signal detection circuit, a compensation switch, and an ESU filter switch. Both switches activate based on an output of the ESU signal detection circuit. A neutral drive feedback loop circuit is configured to compensate for a phase change characteristic of an ESU filter circuit.
