Pull-up load NMOS pull-up suffers from body effect affecting gain accuracy PMOS pull-up is free from body effect but subject to PN mismatch Gain accuracy is the worst for resistive pull-up as resistors poly diffusion well etc dont track transistors.
55 Literature Review Design Project. Ad-ditionally we present hierarchical pipelined comparators which can be optimized for delay area or power consump-tion by using either design in different stages. The Op-amp comparator compares one analogue voltage level with another analogue voltage level or some preset reference voltage VREF and produces an output signal based on this voltage comparison.
