Setting a discharge rate and a charge rate of a relaxation oscillator circuit

Image Number 19 for United States Patent #8058937.

An apparatus and method for setting a ratio of a discharge rate to a charge rate for measuring a capacitance on a sensor element of a sensing device. The apparatus may include a sensor element of a sensing device, a relaxation oscillator having a first and a second programmable current source, and a ratio decoder to receive a ratio of a discharge rate to a charge rate, and to set the first and second programmable current sources based on the received ratio.
