<P>PROBLEM TO BE SOLVED: To provide a detector and a gyrosensor that realizes low-noise sensitivity adjustment. <P>SOLUTION: The detector includes a drive circuit 40 and a detection circuit 60. The detection circuit 60 includes an amplifying circuit 70 for amplifying an output signal from an oscillator 10, a sensitivity adjustment circuit 80 for variably controlling the gain and adjusting the sensitivity, and a synchronization detection circuit 100 for implementing synchronization detection from a reference signal RS. The sensitivity adjustment circuit 80 is provided at a pre-stage of the synchronization detection circuit 100 and operates as a variable gain amplifier and as a high-pass filter. <P>COPYRIGHT: (C)2008,JPO&INPIT |
