This paper presents an area- and power-efficient TX/RX-isolation switch implemented in a 3072-ch ultrasound transceiver IC. The proposed dynamic gate-source shunt topology, which utilizes a negative-HV-transmit-driven shunt switch, eliminates area- a

We report on a new design approach for X-Y symmetric resonator, that can be mechanized as rate (RG) or rate-integrating gyroscope (RIG), with a single digit as-fabricated frequency split between the two mechanical out-of-phase operational modes. We e

Threshold-voltage (Vth) fluctuation due to random telegraph signal (RTS) in flash memory was observed for the first time. A large amount of data of Vth fluctuation was acquired by using a 90-nm-node memory array, and it was confirmed that a few memor

By monochromatically illuminating the tunnel junction between molybdenum disulphide and the tip of a scanning tunneling microscope (STM), the photo-induced tunneling current (ΔI) was detected. By measuringΔI as a function of wavelength, the local a
