ABSTRACT:
A low cost, easily manufactured analog to digital converter uses MOS switching technology easily combined on an integrated circuit with other signal processing circuitry. An input capacitor stores an input analog voltage, and a pumping capacitor is switchably connected to the input capacitor to charge or discharge that input capacitor to a reference value. The number of charge or discharge events is used to generate a digital value for the input analog voltage.
