A Low-power Design developer specializes in designing and developing electronic systems and circuits that consume less energy, thereby increasing battery life and reducing heat production. They optimize power usage during the design phase, employing techniques like dynamic voltage scaling, power gating, and clock gating. They also work on reducing leakage current and static power dissipation. Their work is crucial in developing energy-efficient devices like mobile phones, laptops, or any battery-operated system. They need to have a deep understanding of digital design, power analysis tools, and low power design methodologies, often working closely with chipset designers and software developers.
