We report an insect-size crawling robot with fast moving speed driven by electrostatically induced self-vibration for the first time. Under an applied DC voltage, the robot with a total mass of 47mg has achieved a forward crawling speed up to 30mm/s (1.5 body lengths per second). Using an integrated on-board capacitor, it can move freely without electrical powering wires for up to 10 seconds with...
Decoupling for power rails that demand large current, such as FPGA core, is difficult. The capacitors required for derived solution requires excessive board area for placement and raise system cost significantly. Switcher with high loop Band Width helps reducing the decoupling needs with all the design improvements. In this paper, we proposed a 3-stage behavioral model for switcher to help PCB designer...
Generating reference signal is indispensable and challenging in ferroelectric random access memory using one-transistor and one-capacitor architecture. This work presents an architecture with random-dynamic reference scheme for high speed and high reliability application. The detailed scheme and operating principle are illustrated. By rewriting memory cells and reference cells simultaneously after...
