Abstract
An oversampled delta-sigma analog to digital converter is used in conjuction with bias resistive means and a single bit digital to analog converter in a feedback loop to permit the utilization of the converter in a system in which the converter elements are supplied with power from the same source which supplies the analog input signal to the converter. Accordingly, a minimum number of on-chip circuit components are provided to extend the operational utility of delta-sigma converter/modulation devices and particularly to permit their utilization in electronic circuit breaker chips and devices.
