Latest Patents

One of Liao's latest inventions is a voltage-controlled oscillator. This device includes an oscillation generator, two inductors, and two amplifiers. The oscillation generator produces two oscillation voltage signals based on a control voltage. Each inductor receives a respective oscillation voltage signal and provides a corresponding input voltage signal. Each amplifier generates a current signal based on its input voltage signal. Notably, when one current signal varies in magnitude according to its input voltage, the other maintains a constant magnitude. These current signals are then combined into an output current signal at a common node of the amplifiers.

Another significant invention by Liao is the multi-order wave voltage-controlled oscillator (VCO). This device comprises a power impedance matching unit, a signal transmitting unit, a harmonic wave eliminating unit, and an oscillation frequency adjusting unit. The power impedance matching unit features an input end, an output end, and a first transmission line that acts as a λ/4-wavelength transmission line based on the wavelength of the output harmonic wave. The signal transmitting unit includes multiple upper inductors connected to the output end and multiple lower inductors connected to the ground end. The harmonic wave eliminating unit consists of multiple transistors that form a multi-order ring loop. The oscillation frequency adjusting unit is equipped with several varactors.
