Description
It has been conjectured that the addition of negative
feedback in an oscillator can reduce the noise generated at
frequencies close to the oscillation frequency f0. In this
thesis the noise of a bipolar transistor used in a Hartley
oscillator configuration is measured for different values of
unbypassed emitter resistance. It is found that the noise is
substantially reduced as the negative feedback introduced by
the emitter resistance is increased. A detailed noise
analysis is included, the results of which predict t he
observed reduction in the oscillator noise. The oscillation
frequency of the test oscillator is approximately 50 Mhz, but
the results are general and can be applied at any frequency.
Included are two listings of computer programs that were u sed
to perform the noise analysis.
