Detailed Solution
Download Solution PDFConcept:
The frequency of oscillation of a tuned-collector oscillator is given as:
\(f=\frac{1}{2\pi \sqrt{LC}}\)
Calculation:
Given:
L = 30 μH and C = 300 pF
\(f=\frac{1}{2\pi \sqrt{LC}}\)
\(f=\frac{1}{2\pi \sqrt{30\times10^{-6}\times300\times10^{-12}}}\)
f = 1677kHz
Tuned-collector or Armstrong Oscillator :
It uses inductive feedback from the collector of a transistor to the base.
The LC circuit is in the collector circuit of the transistor.
The following circuit diagram shows the arrangement of a tuned base oscillator circuit:
