Semiconductor optical amplifier pattern effect suppression for return-to-zero data using an optical delay interferometer
(Society of Photo-Optical Instrumentation Engineers, 2010)
An optical delay interferometer ODI is employed to suppress the pattern effect manifested on a 10 Gb/s return-to-zero RZ data stream when amplified by a semiconductor optical amplifier SOA operated in deep gain ...

LDO compensation with variable Miller series resistance
(The Institution of Engineering and Technology, 2014)
A new compensation method for low dropout (LDO) voltage regulators is proposed, where the series resistor of the conventional Miller compensation changes with the load current to track the variations in the first non‐dominant ...

An open-phase fault detection method for six-phase induction motor drives
(2017-04)
Induction machines (IM) with multiple sets of three-phase windings are a real alternative in safety- critical applications due to their inherent redundancy and extra number of freedom degrees. These properties ...
