Abstract
Techniques for generating digital outputs as stochastic bitstreams with activation function mapping are provided. In one aspect, a system includes: a shared circuitry component including a RNG for generating a sequence of random addresses to read a random sequence of digital voltage references stored in a LUT, and a DAC for converting the random sequence of digital voltage references into random analog voltage references V; and a comparator(s) for comparing the random analog voltage references Vand input analog voltages Vin sequences of comparisons to produce sequences of digital pulses as stochastic bitstreams. A system having multiple comparators for simultaneously comparing each of the random analog voltage references Vagainst more than one of the input analog voltages Vin parallel is also provided, as is a method for generating digital outputs from input analog voltages V.
