It is predicted that the required wireless communication capacity will become 1000 times higher every 10 years. Many wireless standards are under discussion to satisfy the unprecedented capacity requirement. For example, the IEEE802.11ay standard is targeting over 100Gb/s data-rate by using the 60GHz band. Unfortunately, the channel bandwidth of 2.16GHz for the 60GHz band is not wide enough to realize...
This paper uses a 6-kA/1.1-kV nondestructive testing system for the analysis of the short-circuit behavior of insulated-gate bipolar transistor (IGBT) power modules. A field-programmable gate array enables the definition of control signals to an accuracy of 10 ns. Multiple 1.7-kV/1-kA IGBT power modules displayed severe divergent oscillations, which were subsequently characterized. Experimental tests...
This paper presents a fully-synthesizable clock and data recovery circuit using injection locking technique. The challenges presented by automated place and route for high speed applications is overcome using background calibration mechanism. The fully-synthesizable all-digital architecture presented in this work is fabricated in 28nm FDSOI technology. The system has a top data-rate of 10.05Gb/s while...
In terms of double-controller design technology and relay feedback identification method an autotuning IMC structure with two degree of freedom (TDF-IMC) is proposed in this paper. The model parameters of the controlled process are identified via a modified relay feedback identification method. The setpoint tracking IMC controller and disturbance attenuation IMC controller are designed, respectively,...
