Latest Patents

One of his latest patents is a phase detector for automatically controlling offset current and a phase-locked loop including the same. This invention features a Gilbert block that outputs a signal proportional to the phase difference between two input signals. It also includes a current source that determines the current in the output terminal, controlled by a reference current signal. Additionally, a converter outputs a current to a second output terminal based on the signal from the first output terminal, while a variable current source adjusts the current output. A controller manages the variable current source in response to the input signals.

Another notable patent is the phase lock detection circuit for a phase-locked loop circuit. This invention relates to a PLL circuit that includes a phase detector, charge pump, loop filter, voltage-controlled oscillator (VCO), frequency divider, and a phase lock detection circuit. The detection circuit features two current charging/discharging circuits with constant current sources that generate a phase lock signal through the charging and discharging of a capacitor. The capacitor's voltage level changes with a hysteresis characteristic, allowing for stable phase lock information.
