Q. Discuss the operation of a transistorized phase shift oscillator with the help of a diagram? Explain the phase shifting circuit?
An oscillator is a circuit which converts electric energy at d.c (zero frequency ) to electric energy at frequency varying from a few hertz to gigahertz . Stated simply , it is a source of alternating voltage or current . An electronic oscillator is, essentially, a feedback amplifier that supplies its own input i.e, it requires not external signal to initiate or maintain the energy conversion process.
The voltage divider R1 - R2 provides DC emitter base bias, Re and Ce configuration provides temperature stability and prevent AC signal degeneration and collector resistor Rc controls the collector voltage. The oscillator output voltage is capacitively coupled to the load by Cc.
