ABSTRACT:
An oversampling converter for converting an analog input signal to a high resolution digital equivalent is provided. The oversampling converter uses sigma delta modulation utilizing single integration. A plurality of quantization circuits provide a plurality of output signals, each output signal containing data information and an error component. Each quantization circuit performs an integration of a difference of an input signal and a feedback signal before quantizing the integrated signal as one of the output signals. A filter, such as a decimation filter, is coupled to the converter for receiving the multiple outputs of the converter and providing a filtered converted digital output signal.
