Abstract
In an example, a system includes a pipelined analog-to-digital converter (ADC) having a main path and an auxiliary path. The main path includes a first stage having a sampling switch, a flash ADC having an input coupled to the sampling switch, a digital-to-analog converter (DAC) having an input coupled to an output of the flash ADC, and a first amplifier having an input coupled to an output of the DAC and the sampling switch. The main path includes a second stage coupled to the first stage and an input of a second amplifier. The main path also includes a backend ADC having an input coupled to an output of the second amplifier. The auxiliary path includes a plurality of metastability comparators coupled to the flash ADC.
