Abstract :
The effects of emitter degeneration on the oscillation frequency, output noise and tuning range of an emitter degenerated LC oscillator designed using bipolar transistors (BJT) is analyzed. Simulation results show increased oscillation frequency, tuning range and carrier-to-noise ratio (CNR). Design guidelines for emitter degenerated LC oscillators are also given.
