Abstract
This paper provides an analysis on how the application of emitter degeneration increases the oscillation frequency while improving the output phase noise and tuning range of LC oscillators designed using bipolar transistors. Design methodology, simulation results and circuit examples for LC oscillators employing this technique are given.
