Latest Patents
One of his latest patents is the "Polar modulation apparatus and method with common-mode control." This invention relates to generating a polar-modulated signal based on separately processed phase modulation (PM) and amplitude modulation (AM) components of an input signal. The apparatus utilizes differential power amplifier circuitry to produce an amplified polar modulated output signal. The bias input of the differential power amplifier is controlled based on the amplitude modulation component, allowing for modulation of a common-mode current. This innovation introduces a new concept of a polar modulator with a static DC-DC converter and controlled output power amplifier.
Another significant patent is the "Quadrature oscillator with high linearity." This invention involves an oscillator circuit and a method for controlling the oscillation frequency of in-phase and quadrature signals. The design includes first and second oscillator means, each with differential oscillator circuits, to generate the respective signals. A frequency control mechanism allows for the variation of the oscillation frequency by adjusting common-mode and tail currents, resulting in a high-frequency IQ oscillator with enhanced linearity.
