The present invention provides a micro-control unit a RC oscillator for generating a reference clock, a plurality of touch switches for generating a transition signal indicating one of the touch switches being touched by human beings, a plurality of analog switches coupled to the touch switches for controlling transmission of the transition signal and a plurality of counters for counting time, all of the counters stop counting when one of the counters overflows and content of all counters being read, wherein ON/OFF of the analog switches controlled by a software.

Apparatus for controlling an electrical cooker and related method thereof

A device and a method for reducing input noise providing at least a microcontroller. The microcontroller comprises: at least a noise reduction device, at least an analog switch and at least a signal output unit. The noise reduction device connected to the ground or a voltage is turned on to charge or discharge a stray capacitor existing on a turned off analog switch so that the amount of charge stored in the stray capacitor is zero or a specific value. Thereby, the noise in a touch switch is reduced and the cost of layout on the PCB is saved.
