CAPACITANCE SENSING CIRCUITS AND METHODS |
摘要 |
A capacitance sense system can include a capacitance sense input configured to receive an input signal that varies according to a sensed capacitance; an integrator/discharge circuit configured to integrate the input signal and discharge the integrated input signal toward the reference level in conversion operations; and a remainder retainer section configured to quantize the discharging of the integrated input signal, and retain any remainder of the integrated input signal that follows a quantization point for a next conversion by the integrator/discharge circuit. |
