Abstract
A method for coding a digital to analog converter of a successive approximation register analog to digital converter includes the steps of first switching capacitors associated with a bit from ground to a reference voltage. Next, a determination is made of whether a logical value of the bit is a first or a second value. If the logical value is the first value, capacitors associated with a next bit are switched from ground to a reference voltage. If the logical value is the second value, one half of the capacitors associated with the bit currently connected are switched from the reference voltage to ground.
