A hybrid experimental system is one of the powerful tools to perform various seismic tests for unknown and/or huge structures, where an actuator-excited experimental vibratory system and a computational response analysis are simultaneously combined and implemented. This paper presents a control methodology for high-performance hybrid experimental systems. A 2-DOF control framework is applied from...
In this paper, a method for controlling the driving current is discussed and then an asymmetric emphasis technique that individually controls its waveform at the rising and falling edges is proposed. The circuit implementation for the asymmetric emphasis technique is discussed and experimental results for the fabricated test chip is provided.
A cell-based forward body-biasing technique to suppress the global process variation and its design flow are proposed. Latch-up free operation is guaranteed by embedded current source cells and limiter cells even when supply voltage is 1.2 V with small area overhead. By applying this technique to a media processor, the worst-case delay is reduced by 20% without sacrificing the maximum leakage spec.
