Title:
物理量検出回路、物理量センサ装置
Document Type and Number:
Japanese Patent JP4794596
Kind Code:
B2
Abstract:
A physical quantity detection circuit (12) is used for a physical quantity sensor (10) that outputs a sensor signal according to a physical quantity given externally. A phase adjustment circuit (100) receives a reference clock (CKref) and operates in synchronization with an operation clock (CKa), to delay a transition edge of the reference clock by a predetermined number of pulses of the operation clock. A detection circuit (104) detects a physical quantity signal from the sensor signal (Ssnc) using a transition edge of a clock (SSS) from the phase adjustment circuit (100) as the reference.
