Multiplexed power generator output with channel offsets for pulsed driving of multiple loads

This disclosure describes systems, methods, and apparatus for a pulsed power supply assembly that distributes pulsed power to two or more loads using a single pulsed power supply. A pulsed power supply of the assembly can phase shift pulses to the different loads to ensure that there is no overlap between pulses at the outputs even where target frequencies and/or duty cycles for the different loads would otherwise call for such pulse overlaps. Variances applied by the pulsed power supply can be limited by attempts to keep average parameters of the pulse trains provided to the different loads to within predetermined variances.

20210247722 · 2021-08-12 ·

Technologies are provided for time-to-digital conversion without reliance on a clocking signal. Some embodiments of the technologies include a clockless TDC apparatus that can map continuous pulse-widths to binary bits represented via an iterative chaotic map (e.g., tent map, Bernoulli shift map, or similar). The clockless TDC apparatus can convert separated pulses to a single asynchronous digital pulse that turns on when a sensor detects a first pulse and turns off when the sensor detects a second pulse. The asynchronous digital pulse can be iteratively stretched and folded in time according to the chaotic map. The clockless TDC can generate a binary sequence that represents symbolic dynamics of the chaotic map. The process can be implemented by using an iterative time delay component until a precision of the binary output is either satisfied or overwhelmed by noise or other structural fluctuations of the TDC apparatus.
