    Abstract: 本発明の発振器は、固定電極23a,23bを有するガラス基板21と、コイルパターン30を有する第2のガラス基板28と、第1及び第2のガラス基板間に配置され、ダイヤフラム26aを有するシリコン基板26と、ダイヤフラム26aを可動させるガス管33とを有する。これにより、インダクタンスLが増加するときには容量Cも増加して共振周波数が低くなると同時に帰還容量が増加する機能を発揮するので、大きな周波数可変範囲で安定した発振が得られる。

    Abstract: Certain aspects of the present disclosure provide techniques and apparatus for generating multiple oscillating signals. One example circuit generally includes a first voltage-controlled oscillator (VCO) having a first inductor and a second VCO having a second inductor in parallel with a third inductor, wherein the second and third inductors are disposed inside a loop of the first inductor and may behave as a magnetic dipole. The loop of the first inductor may be symmetrical, and a combined geometry of loops of the second and third inductors may be symmetrical. The coupling coefficient (k) between the first inductor and a combination of the second and third inductors may be small (e.g., k

    Abstract: A tunable oscillator circuit is disclosed. The tunable oscillator circuit includes an inductor/capacitor (LC) tank circuit comprising a primary inductor coupled in parallel with a first capacitor bank. The LC tank resonates to produce an oscillating voltage at a frequency. The tunable oscillator circuit also includes a 90 degree phase shift buffer coupled to the LC tank and a transconductor. The transconductor is coupled to the 90 degree phase shift buffer and a secondary inductor. The tunable oscillator circuit also includes a secondary inductor that is inductively coupled to the primary inductor and receives a gain-scaled oscillating current from the transconductor. By changing the transconductance, the gain-scaled oscillating current in the secondary inductor will change, thus the effective primary inductance and the oscillation frequency can be tuned.

    Abstract: A VCO includes a transformer-based resonator that has a first LC tank and a second LC tank. The resonator has an even resonant mode and an odd resonant mode. The VCO further includes an active transconductance network that is coupled to a two-terminal port of the first tank and is also coupled to a two-terminal port of the second tank. A first terminal of the port of the first tank is capacitively coupled to a first terminal of the port of the second tank. A second terminal of the port of the first tank is capacitively coupled to a second terminal of the port of the second tank. The active transconductance network causes the resonator to resonate in a selectable one of the even and odd resonant modes depending on a digital control signal. The VCO is fine tuned by changing the capacitances of capacitors of the tanks.
