Hybrid systems combine Large-Area Electronics (LAE) with high-performance technologies (e.g., silicon CMOS) [1]. With architectural concepts for hybrid systems broadening to match the range of emerging applications, this paper examines modular approaches for multi-sheet, multi-technology integration. It identifies the interfaces required as a critical backbone. For interfaces associated with various...
We review our recent work showing that Si and InP Mach-Zehnder modulators can have similar performance, while the first offer the advantage of monolithic integration with electronics. Development status of modulators in photonic BiCMOS is presented.
We present results for FEOL integration of Silicon electro-optic waveguides with high-performance BiCMOS technology. The new technology allows for dense co-integration of high-speed analogue RF circuits and Silicon modulators.
The brain is a perfect example of an integrated multi-scale system, as the complex interactions taking place at the molecular level regulate neuronal activity that further modifies the function of millions of neurons connected by trillions of synapses, ultimately giving rise to complex function and behavior at the system level. Likewise, the spatial complexity is accompanied by a complex temporal...
The paper discusses the operational domain of three phase voltage source converters (VSC) connected to an ac grid. The effects of the parameters (X/R ratio) of the conductors between the VSC and grid on the active and reactive power transfer are analyzed. The impacts on the control parameters, namely, the power angle and output voltage of VSC have been described. The study has revealed the active...
The forebrain, brainstem and spinal cord contribution to the control of locomotion is reviewed in this article. The lamprey is used as an experimental model since it allows a detailed cellular analysis of the neuronal network underlying locomotion. The focus is on cellular mechanisms that are important for the pattern generation, as well as different types of pre- and postsynaptic modulation. This...
