Latest Patents

Yamazaki's latest patents include a saturation prevention system for radio telephones that utilizes both open and closed loop gain control systems. This innovative output power control system is designed to prevent saturation by limiting total output power while maintaining closed loop responsiveness. The system determines when the total output power exceeds a specific trigger level and automatically enters a saturation prevention mode. This mode reduces total output power by modifying a closed loop power control register. The system continuously monitors output power through an output detector and an output comparator, or by sampling output power levels with an analog-to-digital converter. Various preferred embodiments of the saturation prevention process include continual monitoring and interrupt servicing, which modify the closed loop power control register to ensure that output power remains below the trigger level.
