  • Oscillator operable in a high impedance mode
    Patent number: 5508665
    Abstract: An oscillator arranged to operate at an oscillation frequency includes a resonant structure 137, preferably a coaxial resonator, selected to resonate at a frequency, and an impedance 210, preferably a transistor 101 based common collector circuit, parallel coupled to said resonant structure 137, having a negative real part with a real magnitude and an imaginary part with an imaginary magnitude, said real magnitude being a function of said imaginary magnitude, said imaginary magnitude selected such that said real magnitude falls within 50% of a maximum at the oscillation frequency.
