- Abstract:
- In this paper the upconversion of g-r noise to oscillator phase noise is analysed for the first time. The treatment of g-r noise sources showing a Lorentzian spectrum is implemented in a time domain noise calculation program using the perturbation method. Measurements and simulations show that the upconverted g-r noise dominates the phase noise characteristics of AlGaAs-GaAs-HEMT oscillators in the frequency range between 10 kHz and 8 MHz besides the carrier
