Abstract
Provided is an algorithmic analog-to-digital converter (ADC). In the algorithmic ADC, the number of preprocessing amplifiers used in a flash ADC is reduced by sharing the preprocessing amplifiers in the flash ADC, and thus chip size can be reduced. In addition, power consumption can be reduced by dynamically decreasing the bandwidth of an operational amplifier included in a multiplying digital-to-analog converter (MDAC) according to a required resolution.
