Biologically-motivated analog-to-digital (A/D) conversion considers the charge-fire cycles of neurons in biological systems as binary oversampled A/D conversion processes. Feedback mechanisms have been hypothesized that coordinate charge-fire cycles in a manner that suppresses noise in the signal baseband of the power spectrum of output spikes, also a central goal of A/D converter design. Biological systems succeed admirably despite the slow and imprecise characteristics of individual neurons. In A/D converters of very high speed and precision, where electronic/photonic devices also appear slow and imprecise, neural architectures offer a path for advancing the performance frontier. In this work, we provide a new analysis framework and simulation results directed toward that goal.
