摘要： In one embodiment of the present invention, at least at one stage of a Sigma-Delta analog-to-digital converter (ADC) is disclosed to include means for receiving a voltage at least one of the inputs of an operational amplifier, the operational amplifier having at least one output coupled to the at least one of the inputs via an at least one integration capacitor, means for transforming the voltage to a current and means for integrating the current on the at least one of the integration capacitors, during integration time and varying the resistance of at least one of a variable resistors coupled to the operational amplifier during integration time.

摘要： An error-corrected representation of an input signal, such as a bioluminescence signal, is generated. An analog representation of the input signal is oversampled and quantized to provide a first-stage digital output and a residual error. The residual error is provided as a second-stage digital output using successive approximation. The first-stage and second-stage digital outputs are used to generate an error-corrected representation of the bioluminescence signal.
