Software-defined networks (SDNs) are novel networking architectures that decouple the network control and forwarding functions from the data plane. Unlike traditional networking, the control logic of SDNs is implemented in a logically centralized controller which provides a global network view and open programming interface to the applications. While SDNs have become a hot topic among both academia...
In this paper, a novel control method for the three-leg based three-phase to two-phase matrix converter is proposed. The instantaneous two input line voltages are used to synthesize the desired output voltages, which can get sinusoidal input currents with unity power factor and two-phase sinusoidal output voltages with 90° angle shift. The biggest voltage transfer ratio can reach 0.866. A double-sided...
In this paper, a low-voltage wideband folded-cascode low noise amplifier (LNA) with inductive drain feedback is designed for multi-standard applications with operation frequency ranging from 1.8 GHz to 5 GHz. The LNA is based on the TSMC 0.18-um RF CMOS process. Two negative feedback paths are adopted to enhance the bandwidth. The measurement results show the performances of S21 above 8.5 dB and noise...
