Abstract
A successive approximation register analog-to-digital converter may include a reference digital-to-analog converter, a successive approximation register, and a top-plate sampled comparator configured to compare a reference signal generated by the reference digital-to-analog converter to an analog input signal in order to generate a comparator output to the successive approximation register. The top-plate sampled comparator may include sampling transistors, sampling switches, non-linear capacitors, and circuitry configured to pre-condition the comparator by maintaining a constant voltage across non-linear capacitors of the top-plate sampled comparator during a sampling phase of the comparator in order to maintain sampling linearity of the top-plate sampled comparator.
