Patent JP-H11317623-A (JP)
Title: Piezoelectric oscillator, oscillator adjustment system and oscillator adjusting method
Inventor: OKA MANABU
IPC: H03B5/32
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To provide a piezoelectric oscillation circuit which reduces the oscillation start time by a simple configuration. SOLUTION: When a monostable multivibrator MM that constitutes a pulse generating part 20 detects the rise of a high potential side power supply VCC, it generates a control pulse P that becomes a high level for a prescribed time. A switch SW goes into an on-state, while the pulse P goes into a high level. Then, power is inputted, terminal voltage of a bypass capacitor C rises rapidly. Thus, it is possible to lead bias voltage of transistors Q1 and Q2 to a stationary state in a short time and to reduce the oscillation start time.
