He holds two patents that showcase his expertise in the field of electronics, particularly in voltage-controlled oscillators and phase-locked loops. His innovative contributions have made a significant impact on the technology landscape.

Latest Patents

One of Oshima's latest patents is for an "Automatic Amplitude Control for Voltage Controlled Oscillator." This invention discloses a circuit and method for calibrating a voltage-controlled oscillator (VCO). The circuit includes a VCO and a bias control circuit coupled to a tail node of the VCO. An amplitude control unit is also included, which determines the amplitude of the VCO output signal based on the voltage present on the tail node. This unit generates a bias voltage based on the amplitude of the VCO output signal and a target voltage, allowing for precise adjustments to the voltage on the tail node.

Another significant patent is the "Low-Jitter Charge-Pump Phase-Locked Loop." This phase-locked loop features a voltage-controlled oscillator and a charge-pump loop filter. The voltage-controlled oscillator includes a varactor with two sets of capacitor cells that adjust capacitance based on different control voltages. The charge-pump loop filter receives update signals based on the phase difference between two clocks, enabling it to adjust voltages across components effectively.
