초록
Provided is a pipeline analog-to-digital converter (ADC) without a front-end sample-and-hold amplifier (SHA). To minimize a sampling error occurring between a flash ADC and a multiplying digital-to-analog converter (MDAC) of a first sub-ranging ADC due to removal of a front-end SHA, a delay time of a preamplifier included in the flash ADC is calculated, and the flash ADC samples an analog input signal later by the delay time than the MDAC. Accordingly, the pipeline ADC can minimize a sampling error without using a front-end SHA, and its chip area and power consumption can be reduced.
