Abstract
A low distortion high frequency oscillator is described, which is a develop ment of the recently proposed f(T)-integrator, in which an amplitude contro l circuit is embedded inside the integrator. Simulation results suggest tha t, for the oscillation range 1-2.6GHz, the total harmonic distortion (THD) of the output current signal is well below 0.5% for the output current leve l at 50% modulation depth (peak-to-peak). The phase noise of the oscillator is simulated to be -72dBc/Hz at 1MHz offset for 1% THD output current.
