The lab reduces the power consumption of integrated circuits, starting from circuit design.
AboutAbout the lab
Making integrated circuits more energy-efficient.
The Tanzawa Lab studies design techniques for making integrated circuits greener.
Shipments of integrated circuits, such as those for IoT devices, LSIs for AI, and driver ICs for power semiconductors, keep growing every year.
As a result, the total power consumption of integrated circuits keeps rising as well, making it important to reduce power at the circuit and system levels.
The lab researches and develops technologies to make digital, analog, memory, and power-supply circuit systems greener.
Key terms
- Integrated circuit
- Many transistors and wires packed onto a single chip; the central component of electronic devices
- Energy harvesting
- Converting energy found in the surrounding environment, such as light, heat, and vibration, into electricity for use
- Power conversion circuit
- A circuit that changes the form of voltage or current to deliver electricity of the required level to a device

ResearchResearch themes
Shipments of integrated circuits, including LSIs for IoT devices and AI, keep growing, and lower power consumption and greener design at the circuit and system levels are becoming increasingly important. The lab conducts research and development on technologies to make greener the digital, analog, memory, and power-supply circuit systems used in these LSIs.
