Abstract
A successive approximation analog-to-digital converter (SA-ADC) includes a reference generator configured to output a first voltage and a second voltage; a comparator, the comparator having a positive input and a negative input thereto, the comparator being configured to receive the first voltage and the second voltage; and a comparator input toggle located between the reference generator and the comparator, wherein the comparator input toggle is configured to receive the first and second voltages from the reference generator and provide the first and second voltages to the comparator, wherein the comparator input toggle is further configured to switch between a first position, in which the first voltage is connected to the positive input, and the second voltage is connected to the negative input, and a second position, in which the second voltage is connected to the positive input, and the first voltage is connected to the negative input.
