Abstract

Certain aspects of the present disclosure provide a probabilistic analog-to-digital converter (ADC). The probabilistic ADC can be configured to convert an analog input into a variable length or variable amplitude pulse, apply the pulse as a switching pulse to a plurality of memory elements, and store a value based on the memory element after the switching pulse is applied. The number of elements to determine the digital value.

Description

technical field [0001] Certain embodiments of the present disclosure relate generally to analog-to-digital converters, and in particular to designing probabilistic analog-to-digital converters. Background technique [0002] An analog-to-digital converter (ADC) is a device that converts a continuous quantity into a discrete-time digital representation. Current analog-to-digital converters are capable of high sampling rates and high linearity, but are typically based on analog circuits, which can have large areas. Currently, the size of the ADC does not allow significant technology node scaling due to its reliance on analog circuitry. Contents of the invention [0003] Certain embodiments of the present disclosure provide a method for analog-to-digital conversion. The method generally includes converting an analog input to a variable pulse, applying the variable pulse as a switching pulse to a plurality of binary memory elements, wherein the plurality of memory elements ar...
