Summary of 2N2222 Phase Shift Oscillator
This article describes a stable single-transistor sine wave generator using a 2N2222 transistor as a phase shift oscillator. The circuit’s frequency can be easily adjusted by changing resistor and capacitor values, ideally keeping them equal for simpler frequency calculation. It works effectively across various input voltages and is easily simulated in PartSim to observe frequency changes.
Parts used in the 2N2222 Phase Shift Oscillator:
- 2N2222 Transistor
- Resistors (R5, R6, R7)
- Capacitors (C1, C2, C3)
A stable single transistor sine wave generator, that works with many values of input voltage. In PartSim you can easily change the value of the resistors and capacitors and observe the effect on the frequency of the oscillator. If you are manually calculating the frequencies, make things simpler by keeping the values of the resistors and capacitors equal (R5=R6=R7 and C1=C2=C3).
