Patent KR-20220020022-A (KR)
Inventor: LEE SEUNG HOON
IPC: H03M1/38
Filed: 2020-08-11
Abstract: The present invention relates to an analog-to-digital converter technology using dynamic register-based switching, which significantly reduces successive-approximation register (SAR) operation loop latency. According to the present invention, an analog-to-digital converter using dynamic register-based switching comprises an SAR analog-to-digital converter (ADC) including two stages to form a pipeline structure, and a residual voltage amplifier connected between the two stages to amplify the residual voltage of the first stage. The SAR ADC is controlled by allowing a dynamic register storing an output signal of a comparator to directly operate a switch of a digital-to-analog converter (DAC) without passing through a control logic.
