Title: Qiming Wu: Innovator in Voltage Controlled Oscillators
Introduction
Qiming Wu is a prominent inventor based in Shanghai, China. He has made significant contributions to the field of electronics, particularly in the development of voltage controlled oscillators (VCOs). With a total of 8 patents to his name, Wu's work has had a considerable impact on the industry.
Latest Patents
Among his latest patents is the "Spectrum shaping voltage to current converter." This invention discloses a voltage controlled oscillator that includes an amplifier receiving a control signal and a feedback signal. The amplifier generates an amplified output signal based on the difference between these signals. Additionally, the VCO features circuitry that produces an oscillating output signal based on the amplifier's output. A feedback amplifier generates the feedback signal based on the amplifier's output, incorporating a first resistor in parallel with a second resistor, which has adjustable resistance.
Another notable patent is the "Replica cascode bias voltage-controlled oscillators." This invention relates to a VCO that utilizes a replica bias circuit to generate a cascode bias voltage. The VCO produces an output periodic signal with a frequency and phase that are less susceptible to voltage swings. This is achieved by using a bias voltage generated in a replica bias circuit that replicates a voltage-to-current converter in the VCO. The bias voltage is regulated according to the power supply voltage, accounting for variations in the power supply.
