The layout area of an SAR ADC is mainly occupied by its DAC capacitor array. Since there are 2 matched unit capacitors employed for a binary-weighted N-bit DAC, selecting a small unit capacitance is the key to reducing the layout area of the capacit...

The Tanh transfer function of the differential pair operating in weak inversion is employed to implement the non-linear pre-amplification for the comparator of the SAR ADC. This non-linear preamplifier achieves a low gain for large input signals ther... Read More about An output code offset-free comparator for SAR ADCs based on non-linear preamplifier and CMOS inverters.
