発振装置
Document Type and Number:
Japanese Patent JP6601710
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an oscillation device, generating a reference clock signal of a digital circuit, capable of improving a phase noise characteristic of the oscillation device.SOLUTION: The oscillation device is comprised of an oscillation circuit 4 formed from an amplifier 1 for oscillation circuit and an electromechanical oscillator 2 such as a crystal oscillator and a rectangular wave conversion part 3 that converts an oscillation signal of the oscillation circuit into a rectangular wave for output. The oscillation circuit is comprised of a clip type oscillation circuit and clips an oscillation signal from a junction between the electromechanical oscillator and a clap capacitance 8 connected therewith in series. The oscillation signal is input into the rectangular wave conversion part having a predetermined voltage gain and converted into a rectangular wave.SELECTED DRAWING: Figure 1
