Abstract
Time-Mode Signal Processing (TMSP) offers a means for offsetting some of the challenges for analog circuit designs when exploiting CMOS circuit processes designed for digital applications. It would therefore be beneficial to provide a digital method for the storage, addition and subtraction of Time-Mode variables as these offer significant benefit to providing TMSP techniques and expanding their exploitation within devices, systems, and applications. While driven by CMOS process challenges the TM circuits outlined may exploit essentially any digital circuit technology since they are based upon delay. The inventors present an approach to TM variables wherein a switched delay unit is exploited and adopted such that the instantaneous phase difference between two rising signal edges can be latched and used to perform various arithmetic operations. Beneficially, the technique allows analog sampled-data signal processing to be implemented within digital circuitry.
