Abstract
Disclosed herein is an analog-to-digital converter having first and second comparator stages, a voltage reference stage, a switching stage, and an encoder. The first comparator stage receives an analog signal and a threshold and outputs a control signal. The voltage reference stage receives the control signal and outputs one of two or more sets of reference voltages. The second comparator stage receives the analog signal, as well as the set of reference voltages output from the voltage reference stage, and outputs a thermometer code in response to comparisons of the analog signal to the reference voltages. The switching stage receives the control signal, and in response thereto, variously couples inputs of the encoder to: bits of the thermometer code output from the second comparator stage, a first potential, or a second potential. Methods for converting analog signals to digital signals are also disclosed.
