AI Technical Summary
Technical Problem
The increasing number of DC-DC converters in power management integrated circuits (PMICs) for mobile communication devices is causing a footprint issue, making it difficult to fit them into miniaturized electronic devices.
Method used
A multi-voltage generation circuit that shares a single current modulation circuit among multiple voltage modulation circuits using a time-division scheme to generate and maintain multiple modulated voltages, reducing the need for multiple DC-DC converters.
Benefits of technology
Concurrently supports multiple load circuits with significantly reduced footprint by sharing a single current modulation circuit, enabling efficient voltage management in miniaturized devices.
