发明名称 OSCILLATION CIRCUIT, OSCILLATOR, ELECTRONIC APPARATUS AND MOVING BODY
摘要 <p>PROBLEM TO BE SOLVED: To provide an oscillation circuit and an oscillator, capable of achieving a low phase noise and a low jitter even at high frequency oscillation, and an electronic apparatus and a moving body using the oscillation circuit or the oscillator.SOLUTION: An oscillation circuit 2 includes: an XI terminal and an XO terminal to which a vibrator 3 is connected; an oscillation part 10 connected to the XI terminal and the XO terminal, for oscillating the vibrator 3; and a feedback part 20, to which the output signal of the oscillation part 10 is input, for outputting a feedback signal to the input of the oscillation part 10. The feedback part 20 includes: a feedback signal generator 22 for magnifying N times (N is a real number greater than 0) the amplitude of an input signal to output; and a phase shifter 24 for shifting the input signal phase to output. The feedback signal generator 22 and the phase shifter 24 are disposed in series in a signal path from the output part of the oscillation part 10 to the input part of the oscillation part 10.</p>
