Abstract
Provided is a multi-bit pipeline analog-to-digital converter (ADC) having a merged capacitor switching structure. In a multiplying digital-to-analog converter (MDAC) used in the multi-bit pipeline ADC, switches are connected between the bottom plates of respective differential capacitors, thereby constantly maintaining a uniform input common mode voltage regardless of an input digital code. Thus, it is possible to improve the operating speed and performance of the MDAC.
