Abstract
An analog-to-digital converter includes a cycle processing unit and a control unit. The cycle processing unit converts an analog input signal into a digital signal having a plurality of bits by performing a plurality of cycle processing on the analog input signal to acquire values of each bit in order from a higher-order bit to a lower-order bit. The control unit controls the cycle processing unit such that a period of the cycle processing is shortened according to a cycled number of the cycle processing.
Claims15
An analog-to-digital converter comprising:
- a cycle processing unit configured to convert an analog input signal into a digital signal having a plurality of bits by performing a plurality of cycle processing on the analog input signal to acquire values of each bit in order from a higher-order bit to a lower-order bit;
- and
- a control unit configured to control the cycle processing unit such that a period of the cycle processing is shortened according to a cycled number of the cycle processing.
An analog-to-digital conversion method in which an analog input signal is converted into a digital signal having a plurality of bits by performing a plurality of cycle processing on the analog input signal to acquire values of each bit in order from a higher-order bit to a lower-order bit, the method comprising a step of:
- controlling the cycle processing such that a period of the cycle processing is shortened according to a cycled number of the cycle processing.
