Method to smooth transitions in an ADC for current regulation

摘要

The present invention is directed at providing methods in a circuit for smoothing transitions relating to a signal processing function. A reference signal is produced that relates to a DAC output code. The reference signal is used as a starting point, and is compared to the input signal. A feedback signal is produced that is used to adjust the reference. The invention can be used to implement signal processing functions such as peak detection, noise filtering, peak suppression, and the like, in which the transitions in the signal are smoothed. The invention can implement these functions with a minimal complexity and a minimal die area.
