  • Publication number: 20080178672
    Abstract: An oscillation driver circuit includes a gain control amplifier which causes a vibrator to produce driving vibrations by controlling an oscillation amplitude in an oscillation loop, and a comparator which generates a synchronous detection reference signal based on a signal in the oscillation loop. The oscillation driver circuit sets a gain in a first oscillation loop including the vibrator and the comparator to be larger than unity using an output from the comparator, and then causes the vibrator to produce the driving vibrations by controlling an oscillation amplitude in a second oscillation loop including the vibrator and the gain control amplifier in at least one of an oscillation startup state and a sleep mode.
