Introduction

Giacomo Castoro is an inventor associated with Trapani, Italy. His work includes a radio transmitter invention involving frequency synthesis and digital calibration. He is credited with 1 patent.

Latest Patents

Castoro’s patent, titled “Radio Transmitter,” describes a frequency synthesizer designed to generate and calibrate its output. A digitally controlled oscillator produces an output clock signal based on a digital control word, and a clock divider derives a divided clock signal from it. A digital-to-time converter uses that divided signal to generate a feedback clock.

The design also includes a time-to-digital converter that determines a phase error from the difference between a reference clock and the feedback clock, while accounting for a bias control word. A loop filter uses the phase error to generate the digital control word for the oscillator. A calibration unit generates a training sequence to identify a gain error and adjusts the bias control word accordingly.

Career Highlights

Castoro is associated with Infineon Technologies Americas Corp. and Infineon Technologies Austria AG. His patent reflects work on frequency synthesis, feedback control, and calibration for radio transmitter technology.
