Abstract :
A flash-TDC hybrid ADC architecture is proposed in this paper. The operating principle relies on measuring the impact of the input amplitude on the delay of the comparators in the flash. TDCs capture this timing information, which is mapped to an output digital code using simple digital logic to provide additional bits of resolution.
