FD79-5

 

Description: Two Transistor Sine Wave Oscillator

This oscillator uses two transistors and operates the crystal in the fundamental mode. C1 and C2 should be about 2 700 pF for 1 MHz, 680 pF for 5 MHz, and 330 pF for 10 MHz. 150 pF can be used for up to 20 MHz. The output is a near perfect sine wave. Try varying C1 and C2 for best waveform. About 2 to 6 Vpp is available. (Reprinted with permission from Popular Electronics, 3/91, p. 92. Copyright Gernsback Publications, Inc., 1991.) From figure FD79-5 of Encyclopedia of Electronic Circuits on CD-ROM Vol. 1.
