With a total of 12 patents to his name, Tan has made remarkable advancements that enhance the performance and efficiency of electronic systems.
Latest Patents
One of his latest patents is the "Agile frequency synthesizer scheme for fast-hopping, low phase noise applications." This invention outlines a system and method for frequency hopping that precalibrates a subset of channels, storing their associated curves in a computer-readable medium. The decision-making circuitry can access these precalibrated curves before hopping to a new channel. If the destination channel has an associated curve, the system utilizes the values from that curve. If not, it identifies a closely situated channel with a precalibrated curve and uses an offset value to settle at the destination channel. The invention also allows for dynamic updates of these offsets.
Another notable patent is the "Differential ring oscillator and method for calibrating the differential ring oscillator." This invention features a differential ring oscillator comprising multiple delay stages connected in a ring. It includes a current source for generating a bias current based on a coarse tuning signal, a latching circuit for producing a differential output signal, and a capacitive array for providing first capacitance according to a fine tuning signal. The system is designed to adjust the oscillating frequency to reach a predetermined frequency range and approach a target frequency.
