The lab designs LSIs to create new ways of delivering power, from IoT devices to power equipment.
AboutAbout the lab
New power delivery through integrated power management
The Takamiya Lab researches power delivery technologies built around LSI design.
Electronics is finding uses in more places, from IoT and wearables to devices implanted in the body, moving from objects to the surface of the body and then inside it.
The key to making this possible is the technology for how to deliver power.
The lab handles a wide range of power levels, from nW in IoT to kW in power electronics, and explores new solutions by combining insights from different fields.
Key terms
- LSI
- A large-scale integrated circuit that packs many transistors onto a single small chip
- Energy harvesting
- A technology that collects small amounts of energy from the surrounding environment, such as light, vibration, and electric fields, and converts it into electric power
- Gate driver
- A circuit that drives the control terminal (gate) of a power transistor to switch it on and off

Using LSI design techniques for "integrated power management," the lab aims to create new power delivery that is small, lightweight, and intelligently controllable. It researches power delivery technologies for IoT nodes, power devices, ultra-thin flexible electronics, and microprocessors.
*Illustrative imageDelivering power to small IoT devices
For small devices such as IoT sensors (IoT nodes), the lab researches energy harvesting, wireless power transfer, DC-DC converters, and battery management.
*Illustrative imageCircuits that drive power transistors intelligently
The lab developed a gate driver IC that can digitally change the current used to drive a power transistor (IGBT). It optimally controls the voltage waveform during switching, reducing both loss and noise at the same time.
