Abstract: The present invention relates to an SAR ADC performing range scaling by processing a signal of a half of a single input signal range by sampling the single input signal in the half of a sampling capacitor. The present invention prevents a voltage loss in a preamplifier and processes the single input signal of a power voltage size in a whole ADC.

Abstract: PURPOSE: A four channel pipe line SAR ADC minimized mismatching between channels is provided to remove amplifier offset mismatching between channels and to minimize electricity consumption and an area. CONSTITUTION: Four channel pipe line SAR ADC comprises a first SAR ADC (100), a remaining voltage amplifier (110), a second SAR ADC (120) and a digital correction circuit (130). For pieces of 6 bit SAR ADC in the first step is composed of SAR ADC with four channels connected in parallel. The remaining voltage amplifier is connected to an output unit of the first SAR ADC and is shared in four channels with a couple of input units. The second SAR ADC is composed of SAR ADC in four channels connected in parallel which tests remaining voltage which is amplified in the remaining voltage amplifier. The digital correction circuit corrects errors of digital output which comes out of the first SAR ADC and the second SAR ADC.

Abstract: 본 발명은 SAR ADC에 관한 것으로서 단일 입력신호를 샘플링 커패시터의 절반에 샘플링하여 상기 단일 입력신호 범위의 절반 크기의 신호를 처리하도록 레인지 스케일링을 수행하는 것을 특징함으로써, 프리앰프에서 전압여유부족이 발생하지 않으며, 전체 ADC에서는 전원전압 크기의 단일 입력신호 처리가 가능하다.
