Title:
A/D CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/116737
Kind Code:
A1
Abstract:
An A/D conversion device comprising first, second, and third pulse delay circuits, first, second, and third pulse passage stage detection circuits, a timing output circuit, and an output circuit. The first pulse delay circuit is comprised of multiple stages of delay units, which delay a first pulse signal, connected together. The first pulse passage stage detection circuit detects a first number of stages. The second pulse delay circuit is comprised of multiple stages of delay units, which delay a second pulse signal, connected together. The second pulse passage stage detection circuit detects a second number of stages. The timing output circuit outputs a timing signal. The third pulse delay circuit is comprised of multiple stages of delay units, which delay a third pulse signal, connected together. The third pulse passage stage detection circuit detects a third number of stages. The output circuit outputs a digital value corresponding to the third number of stages.
