ABSTRACT:
An analog-to-digital converter (ADC) includes a modulator and a decimation filter. The modulator includes a sampling circuit, integrator, a quantizer, and feedback circuitry. The sampling circuit includes at least one sampling capacitor and a plurality of dump capacitors. A sum of the capacitance of the dump capacitors is substantially equal to a capacitance of the sampling capacitors. Combined sampling/dump capacitors having approximately equal capacitance may be used with the sampling circuit.
