Estimating the term…
In an analog-to-digital converter, when a capacitive element with a small capacitance is used in order to reduce power consumption, the characteristics of the analog-to-digital converter deteriorate due to the variation in the specific accuracy. Further, the method of reducing the variation with the specific accuracy causes an increase in the size of the circuit and power consumption. An analog-to-digital converter includes an analog core unit having at least one capacitive element. The capacitive element includes a capacitive bank having plural capacitive element units having substantially the same capacitance value, and the capacitive bank is configured to select one capacitive element unit from the plural capacitive element units with substantially equal probability.
An analog-to-digital converter comprising:
A wireless transceiver circuit, comprising:
A control method of an analog-to-digital converter that includes a multiplying digital-to-analog converter, and at least some of capacitive elements of the multiplying digital-to-analog converter are embodied selecting a specific capacitive element unit from a capacitive bank configured by the plurality of capacitive element units having substantially the same capacitance value with substantially equal probability, the control method comprising steps of:
