Analog-to-digital conversion device for multiple input signals and conversion method therefor |
摘要 |
An analog-to-digital conversion device for multiple input signals includes a sample-and-hold amplifier and an analog-to-digital converter for converting an analog signal output from the sample-and-hold amplifier into a digital signal. According to the analog-to-digital conversion device for multiple input signals and a conversion method therefor, even if an input buffer is not provided, the dynamic range of the analog-to-digital converter may be optimally set depending on the input signals, and current consumption may be reduced. |

1. An analog-to-digital conversion device, comprising:
a sample-and-hold amplifier; an analog-to-digital converter for converting an analog signal, output from the sample-and-hold amplifier, into a digital signal, wherein an amplification gain of the sample-and-hold amplifier is controllable; and a reference signal generator for generating a reference voltage that is capable of being used to set a dynamic range of the analog-to-digital converter, wherein the reference voltage is adjusted depending on a swing range of a signal output from the sample-and-hold amplifier. |
