ABSTRACT:
An analog-to-digital (A/D) converting device according to the idea of the vernier caliper is provided. First, an analog signal is input into a primary A/D converting circuit to obtain a most significant bits (MSBs) of the digital signal. Then, the MSBs are input into a secondary A/D converting circuit to obtain a least significant bits (LSBs) of digital signal. Finally, the digital signal is obtained by merging the MSBs with the LSBs. Compared with the conventional flash A/D converting device, the present invention significantly reduces the quantity of the required components (for example, the amount of resistors and comparators), such that cost and power consumption are reduced. Compared with the conventional two-step A/D converting device, the present invention effectively eliminates the loading effect and provides a faster speed of signal conversion.
