Abstract
A new technology for simultaneously performing the previously separate functions of analog phase-tracking and A/D conversion, represented by a family of systems referred to as delta-sigma frequency-to-digital converters (.DELTA..SIGMA.FDCs). Each system uses coarse analog phase measurements, quantization noise shaping, and decimation filtering to perform instantaneous frequency-to-digital conversion. Because they operate on instantaneous frequency in the manner that .DELTA..SIGMA. modulators operate on amplitude, they share many of the benefits enjoyed by .DELTA..SIGMA. modulator-based A/D converters such as reduced analog circuit requirements and amenability to VLSI implementation.
