Latest Patents

One of Gramegna's latest patents focuses on output power control of an RF amplifier. This innovation enhances the precision and reliability of a current-limited mode output power control by sensing the base current of the output power transistor. The base current is compared to a control current that is normalized based on the current gain of a bipolar junction transistor with similar characteristics. This method effectively compensates for the fabrication process spread of current gain figures, ensuring consistent output power across varying temperatures and process variations.

Another significant patent involves a device for calibrating the frequency of an oscillator. This device generates a calibration signal that is applied to the oscillator to ensure accurate output frequency. It utilizes a counter to compare the counted time window number with a prefixed time window number, adjusting the calibration signal as necessary until the two values align. This innovative approach enhances the reliability of frequency calibration in oscillators.
