Abstract
Systems and methods are related to a successive approximation analog to digital converter (SAR ADC). In one aspect, a method includes sampling, by a sample and digital to analog conversion (DAC) circuit, an input voltage to obtain a sampled voltage. The method also includes determining, by a comparator coupled to a set of storage circuits, a state of a plurality of bits corresponding to the sampled voltage. The comparator has a current parameter or voltage parameter adjusted based upon a conversion margin. Adjustment of the current parameter or the voltage parameter affects speed of determining the state of the bits. The method also includes storing the bits in the set of storage circuits. In some aspects, an SAR ADC is configured to perform the method.
