Abstract
An SAR ADC combined with a flash ADC includes a clock generator, a DAC and a comparator. The SAR ADC combined with the flash ADC further includes an SAR logic unit using a successive approximation register control to determine, while a clock signal is a first state that is either high or low, a part of digital bits of the input signal based on a signal outputted from the comparator and control the DAC to generate a first analog signal based on the first determined digital bits and a flash ADC using a flash control to determine, during a second state switched from the first state, a remaining part of the digital bits of the input signal based on the first analog signal and control the DAC to generate a second analog signal based on the second determined digital bits in the second state.
