摘要： A novel and useful 60 GHz frequency generator based on a third harmonic extraction technique which improves system level efficiency and performance. The frequency generator employs a third harmonic boosting technique to increase the third harmonic at the output of the oscillator. The oscillator generates both ˜20 GHz fundamental and a significant amount of the third harmonic at ˜60 GHz and avoids the need for a frequency divider operating at 60 GHz. The undesired fundamental harmonic at ˜20 GHz is rejected by the good fundamental harmonic rejection ratio (HRR) inherent in the oscillator buffer stage while the ˜60 GHz component is amplified to the output. The fundamental harmonic is further suppressed by active cancellation by properly combining the two outputs. The oscillator fabricated in 40 nm CMOS exhibits a phase noise of −100 dBc/Hz at 1 MHz offset from a 60 GHz carrier and have a tuning range of 25%.

摘要： A starter is provided for a self-oscillating radio frequency oscillation circuit for high-power applications used for plasma generation in an ICP emission spectrometer or for other purposes. A secondary winding of a starting transformer is arranged in an LC resonance circuit including an induction coil, capacitor and other elements. A starter, e.g. a Clapp oscillator circuit, is connected to a primary winding magnetically coupled with the secondary winding. A radio-frequency current is induced in the LC resonance circuit by energizing the starter for a certain period of time in a starting phase. As a result, electric current flows through the secondary windings in a full-bridge drive circuit which are magnetically coupled with primary windings, whereby voltage is developed between the gate and source of MOSFETs, causing these MOSFETs to begin an ON/OFF operation, whereby the self-oscillation is started.

摘要： The present disclosure relates to a device and method to reduce voltage headroom within a voltage-controlled oscillator by utilizing trifilar coupling or transformer feedback with a capacitive coupling technique. In some embodiments of trifilar coupling, a VCO comprises cross-coupled single-ended oscillators, wherein the voltage of first gate within a first single-ended oscillator is separated from the voltage of a second drain within a second single-ended oscillator within the cross-coupled pair. A trifilar coupling network is composed of a drain inductive component, a source inductive component, and a gate inductive component for a single-ended oscillator, wherein a coupling between drain inductive components and gate inductive components between single-ended oscillators along with a negative feedback loop within each single-ended oscillator forms a cross-coupled pair of transistors which reduces the drain-to-source voltage headroom to approximately a saturation voltage of a transistor within the cross-coupled pair. Other devices and methods are also disclosed.
