Summary:A low power capacitive detector is disclosed. The detector includes a mechanism to measure and detect touch on capacitive sensors. The detector uses signal processing to suppress noise and increase sensitivity. The detector does not require dedicated analog circuitry, making it easy to adopt in a microcontroller system. The detector can be scaled to a larger number of capacitive sensors without noticeable increase in silicon cost.
