Abstract
Disclosed are a circuit and a method for an analog-to-digital conversion with programmable resolution. The circuit includes a resistor ladder comprising a plurality of resistors coupled to a plurality of comparators; wherein the resistor ladder is further coupled to a switch logic circuit and a plurality of current sources; and wherein the switch logic circuit is configured to control an operation of a plurality of switches to alter conversion resolution of the ADC, and an error correction circuit coupled to the outputs of the plurality of comparators, wherein the ADC is configured to perform a first conversion step and a second conversion step, and wherein the ADC is configured to perform only the first conversion step when programmed for lower conversion accuracy and higher conversion speed.
