In this study, a high-efficiency wireless power transfer (WPT) coil that is robust against interoperability and misalignment was developed by applying an inductive system to drone. The transmitting had ferrite plate applied helical structure included the receiving part. guard-type part sheet. To analyze spiral coils according winding method, z-axis magnetic field vector analyzed. A suitable WPT model for each drone analyzing mutual inductance based on whether attached transmitter or receiver...
A high-speed and high-gain modulator driver circuit is presented using 4-inch InP SHBT technology. The IC was developed for driving EAM modulators in 40 Gbit/s optical fibre systems. monolithic integrated features output amplitude control crossing point control. Measured results show the operates at with a swing of 2.5 Vp-p each 9/8 ps rise/fall times. power dissipation 1.5 W standard supply −5.2 V.
A complete 40 Gb/s front-end chip set for optical transmission systems will be presented The analog includes modulator drivers on the transmitter site, and transimpedance amplifier, limiting amplifier automatic-gain-controlled (AGQ amplifier) receiver site. All circuits were designed, fabricated in SHBT technologies successfully tested above at first run.
