Title: Oscillator circuit
Inventor: NAKAMOTO HIROYUKI
IPC: H03B5/12
Filed: 1999-12-24
Abstract: PROBLEM TO BE SOLVED: To stably obtain a drive signal for driving a laser diode and to enhance its output. SOLUTION: An oscillator output signal from an oscillator is amplified by an output amplifier, and then applied to the laser diode LD. The diode LD is turned ON at each high frequency.

Since the amplifier is operated in a boundary between a linear region and a saturated region, unevenness in the output signal is suppressed. A diode element (Tr3) is connected in series with a negative feedback resistor R2 to increase its output.
