Transistor Oscillator Frequency. The frequency f is in hertz whereas l and c are inductance mh and capacitance µf respectively. Sine wave oscillator low frequency constant amplitude.
You really could use any npn transistor. 5 crystal oscillator circuits using cmos. In colpitts oscillator the capacitive voltage divider setup in the tank circuit works as the feed back source.
The 2n4401 transistor is an npn transistor.
Sine wave oscillator low frequency constant amplitude. Relaxation oscillator built with a transistor. The tank circuit is oscillating which causes the transistor to switch between saturation and cutoff. A standard 465 khz if transformer t1 intended for transistor circuits is the lc resonant tank circuit in this oscillator.
