Abstract
A multi-stage analog-to-digital converter (ADC) suitable for low power applications, such as glucose monitoring, may be required to digitize a slow-moving signal. As such, a multi-stage ADC must be versatile. Accordingly, the multi-stage ADC can be configured to operate at different bandwidths and resolutions through the use of ADC stages that can be enabled or disabled in an exchange between resolution and speed. Each ADC stage digitizes an input signal (e.g., a voltage or a current) using an analog comparison to access a lookup table for a digital signal that represents the input signal at a particular accuracy. Unlike other multi-stage approaches, the digitization is asynchronous (i.e., requires no clock) and can provide simplicity, speed, and low-power operation to the multi-stage ADC.
