<p num="1"><br/><br/><br/>A thermocouple measuring circuit for sensing a temperature at a measuring <br/>point is provided. The thermocouple measurement circuit (12) includes a <br/>thermocouple input for sensing a temperature at a measuring point, a <br/>compensation circuit (14) for compensating thermocouple effects of junctions <br/>of the thermocouple, and an instrumentation amplifier (16) for summing an <br/>output of the thermocouple and an output of the compensation circuit and <br/>outputting a voltage indicative of the temperature sensed, wherein the output <br/>of the compensation circuit is a reference voltage for the output of the <br/>instrumentation amplifier. Various embodiments of the thermocouple measurement <br/>circuit may be employed in electrosurgical generators for controlling output <br/>power dependent on temperature conditions.<br/>
