説明

A double-tail type comparator has been known as a low power consumption used in Successive approximation resister type Analog to Digital Converter (SAR ADC). However, in the case of the wide input common mode voltage range is required, it is necessary to change the circuit configuration. In this paper, we designed a comparator with a wide input common-mode voltage and a ultra-low voltage operation. Our proposed comparator improved the input common-mode voltage by about 50% , and the power consumption achieved to same as the conventional one.
