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