Latest Patents

One of Younghua Song's latest patents is centered around a low leakage power management system. This innovative system selectively couples an external voltage domain to the internal voltage domain of an integrated circuit based on the demand for its functions. When the integrated circuit is active, the external supply voltage is connected to its internal supply voltage plane. Conversely, during idle periods, this external supply voltage is disconnected from the integrated circuit chip. The design includes multiple switch cells that facilitate the connection of the external voltage to the integrated circuit. Additionally, a multi-step sequence is implemented to connect the external supply voltage to the chip's internal supply voltage plane, effectively preventing excessive current from flowing through any individual switch cell.
