Title: Yasuyuki Ohnishi: Innovator in Semiconductor Technology
Introduction
Yasuyuki Ohnishi is a prominent inventor based in Kyoto, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 5 patents. His work focuses on enhancing the efficiency and performance of semiconductor devices.
Latest Patents
One of Yasuyuki Ohnishi's latest patents is a semiconductor device equipped with a voltage step-up circuit. This innovative device features a step-up circuit that includes multiple charge pump units. Each unit is designed with a well separation type MOS transistor. The separation well of the transistor is connected to a high potential, creating double reverse biases between the N-type well and a P-type substrate, as well as between the N-type well and a P-type well. This design allows the threshold voltage (Vth) of the MOS transistor to be maintained at a low level. Additionally, the units are equipped with a clock whose current supply capability is limited until certain conditions are met. This limitation helps to suppress power consumption during startup, thereby minimizing fluctuations in the supply voltage.
