Single-junction transistor sine wave oscillator circuit

Posted on Feb 5, 2014

The single-junction transistor is always used in the sawtooth generator and pulse generator, and it also can form the simple sine wave generation circuit. As an oscillator circuit of the discrete component, it uses fewest components. As the figure shown, compared with the simple single-junction tube remittent oscillator circuit, this circuit adds

a LC tuned circuit at the second base. By the excitation of the single-junction tube current pulse, the tuned circuit generates sine wave oscillation. Tuned resistor R1 can control the size of current pulse and have the sine wave at B2.
