- Abstract
- Provided are a method of algorithmic analog-to-digital conversion and an algorithmic Analog-to-Digital Converter (ADC). The algorithmic ADC includes a Multiplying Digital-to-Analog Converter (MDAC). The MDAC includes a Digital-to-Analog Converter (DAC) for converting a first digital signal into an analog signal, a subtractor for calculating a difference between the signal output from the DAC and an analog signal input from a first Sample and Hold Amplifier (SHA), an amplifier for amplifying the difference, a first capacitor unit connected with an output end of the first SHA and an input end of the amplifier through a first switching unit, a second capacitor unit connected with the input end and an output end of the amplifier through a second switching unit, and a third capacitor unit connected with the input end and the output end of the amplifier through a third switching unit.
