Abstract
Various embodiments relate to a single slope analog to digital converter (ADC), including: a voltage slope generator configured to generate a voltage slope based upon a fixed current and variable current; an analog comparator configured to compare a voltage to a voltage output from the voltage slope generator; a first register configured to store a first count based upon a reference voltage being input into the analog comparator; a second register configured to store a second count based upon an input voltage being input into the analog comparator, wherein the input voltage is the voltage to be converted to a digital value by the ADC; and a digital to analog converter (DAC) configured to produce a slope trim signal based upon the voltage slope output by the voltage slope generator, the first count, and a count target associated with the voltage reference, wherein the variable current in the voltage slope generator is based upon the slope trim signal.
