SIGNAL CONVERTER AND METHOD OF SIGNAL CONVERSION

摘要

A signal converter and a method for converting a signal reduce power consumption and a layout area by applying a sharing technique and a switching technique together. A signal converter(100) includes a first amplifier always maintaining the active state, and a third amplifier maintaining the active state in a first phase and a second amplifier maintaining the active state in a second phase. While a plurality of first capacitors(C1) sample the input signal in the first phase, the serially connected first amplifier and the third amplifier amplify the voltage generated by the first voltage set. While a plurality of second capacitors(C2) sample the output voltage of the second amplifier in the second phase, the serially connected first amplifier and the second amplifier amplify the voltage generated by the second voltage set.
