摘要： In one embodiment, an analog to digital converter (ADC) for converting an analog signal to a digital signal includes an input channel for receiving the analog signal, and includes a first and second sampling-integrating units. The first sampling-integrating unit receives the analog signal, samples the analog signal, integrates a superposition of a first feedback signal and a sampled signal of the analog signal, and generates a first output signal. The second sampling-integrating unit receives the first output signal, samples the first output signal, integrates a superposition of a second feedback signal and a sampled signal of the first output signal, and generates a second output signal. The ADC includes a feedback circuit for generating the digital signal according to the second output signal and for providing the first and second feedback signals indicative of the digital signal to the first and second sampling-integrating units respectively.

摘要： Interface unit for voltage input signals comprising two or more input channels. The input signals of these two or more input channels are connected alternately by an analog multiplexer to an analog-to-digital converter. The A/D converter comprises an integrated sigma-delta modulator circuit which generates a digitized 1-bit signal representing the input signal voltage level for a control unit irrespective of whether the input channel signal is digital or analog. By means of the invention all input voltage channels are made similar such that the input channels of the interface unit can receive an analog or digital signal irrespective of each other.

摘要： A method and system for selecting implementation of a filter controller between a single conversion that ensures a fully-settled converted output and a continuous conversion of an input signal are disclosed. State machine determines whether convert start signal has a duration, which ends on or before a first occurrence of a conversion done on the input signal. Conversion done is an occurrence of when a bit set has been converted from the input signal. If convert start signal has a duration which ends on or before the first occurrence of conversion done, then state machine selects and implements single conversion of the input signal. Digital system ensures a fully-settled converted output by waiting for the filter to receive and filter a predetermined number of bit sets for a conversion output and then outputting the conversion output. Otherwise, state machine selects and implements continuous conversion of the input signal.
