  • Publication number: 20100013502
    Abstract: In an evaluation method, voltages at ends of a to-be-measured capacitor and a capacitance-adjustable circuit are switched in response to a first set of clock signals so as to adjust an integrated voltage to be a sum of the integrated voltage and a first difference voltage. Next, whether a first control event is received is judged. If not, the previous step is performed. If yes, an integration operation is performed to switch a voltage of an end of a known capacitor in order to adjust the integrated voltage to be a sum of the integrated voltage and a second difference voltage. Next, whether an integrating period ends is judged. If not, the first step is repeated. If yes, a capacitance of the to-be-measured capacitor is obtained according to the number of times that the integration operation is performed in the integrating period and a capacitance of the known capacitor.

  • Publication number: 20090243631
    Abstract: A measurement method for capacitance includes the following steps. First, a voltage on at least one end of a to-be-measured capacitor is switched in response to a first set of clock signals such that a level of an integrated voltage is adjusted from a start voltage level to an end voltage level in a first integration period, wherein a capacitance of the to-be-measured capacitor is relevant to a difference between the end voltage level and the start voltage level. Next, the level of the integrated voltage is adjusted from the end voltage level to the start voltage level in a second integration period in response to a second set of clock signals. Then, the capacitance of the to-be-measured capacitor is obtained according to the first and second integration periods and a known characteristic parameter.
