Abstract
A digital voltage regulator including a dual rail delay chain having large size, feed forward cross-coupled inverters that interconnect the two rails. Stages of the delay chain include a dual-ended output that provides a data signal and a substantially simultaneous data complement signal to a flip-flop component associated with a sampling circuit. In use, the enhanced resolution delay chain and the reduced metastability window flop-flop increase the precision of the digital voltage regulator.
