Latest Patents

One of Kazunori Torii'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, where the separation well is coupled to a high potential. This configuration creates 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 reducing fluctuations in the supply voltage.
