Title:
GYRO OUTPUT DETECTION METHOD
Document Type and Number:
Japanese Patent JP3201054
Kind Code:
B2
Abstract:
PURPOSE: To obtain a detection circuit which can reduce drifting without using a variable resistor etc.
CONSTITUTION: Two piezoelectric elements 16a and 16b for detecting a vibration gyro 12 are connected to a differential amplification circuit 38 and a cumulative amplification circuit 48. The output of the differential amplification circuit 38 is detected by a first synchronization detection circuit 40 and further is smoothed by a first smoothing circuit 42. The output of the cumulative amplification circuit 48 is detected by a second synchronization detection circuit 50 and further is smoothed by a second smoothing circuit 52. The output of the first smoothing circuit 42 and the second smoothing circuit 52 is output from a synthesis circuit 54.
