发明名称 Resonator having distributed transconductance elements
摘要 An apparatus comprises a resonator including a plurality of switched impedances spatially distributed within the resonator and a corresponding plurality of transconductance elements distributed within respective distances among the switched impedances. The resonator has a given desired resonant frequency and a given amplitude of response. Combined pairs of the switched impedances and transconductance elements have respective parasitic resonant frequencies which are higher than the given desired resonant frequency and have respective amplitudes of response which are lower than the given amplitude of response. The apparatus may be a voltage controlled oscillator or an active filter.

主权项 1. An apparatus comprising: a resonator comprising: a plurality of switched impedances spatially distributed within the resonator; anda corresponding plurality of transconductance elements distributed within respective distances among the switched impedances; wherein the resonator has a given desired resonant frequency and a given amplitude of response; wherein combined pairs of the switched impedances and transconductance elements have respective parasitic resonant frequencies which are higher than the given desired resonant frequency and have respective amplitudes of response which are lower than the given amplitude of response; wherein the switched impedances have different magnitudes and the transconductance elements are non-uniformly distributed within the resonator.
