ABSTRACT:
In a wireless chip receiving the multi-rate data according to the related art, power consumption and a circuit area of an analog-to-digital converter become large. In a digital calibration type analog-to-digital converter including both a reference analog-to-digital conversion unit and a main analog-to-digital conversion unit, when processing the high-sample rate wireless receive signal, both the reference analog-to-digital conversion unit and the main analog-to-digital conversion unit are operated to configure a general digital calibration type analog-to-digital converter, and when processing a low-sample rate wireless receive signal, analog-to-digital conversion is performed by using the reference analog-to-digital conversion unit and operations of the main analog-to-digital conversion unit or the like are stopped to remarkably reduce power consumption.
