Abstract
An oven temperature control circuit utilizes one or more light emitting diodes to establish a clamping voltage that limits the voltage at the input of a circuit component, such as an analog-to-digital converter, when a sensor, such as a thermistor, is connected to the input of the circuit component and the sensor is subjected to an EMI pulse. A method is provided for continued execution of a heating process after an unavoidable and unintentional interruption.
