Abstract
A method for operating a SAR assisted pipelined ADC includes enabling a SAR ADC in a current stage circuit for converting an input analog voltage into a digital code during a first time interval, resetting an operational amplifier of an MDAC in the current stage circuit during the first time interval, maintaining the SAR ADC of the current stage circuit in an enabled state for outputting during a second time interval, and enabling the MDAC in the current stage circuit during the second time interval. The method also includes enabling the SAR ADC in the current stage circuit for sampling during a third time interval and connecting the output terminal of the MDAC in the current stage circuit to the input terminal of the next stage circuit during the third time interval. The first, second, and third time intervals are continuous and do not overlap each other.
