Abstract
A touch sensing system includes a charge distributor, a pre-amplifier, an analog-to-digital converter (ADC), and a temperature compensating device. The temperature compensating device varies one or more of a first reference voltage supplied to the charge distributor, a second reference voltage supplied to the pre-amplifier, and the capacitance of the charge distributor, in response to temperature data from a temperature sensor.
