Same frequency networking (SFN) technology is widely used in modern wireless network to achieve high area spectrum efficiency. However, it brings the inter-cell interference to the users at the cell edge. Frequency allocation and power control is extensively used to diminish the effect of the interference. Most of the researches are focus on the downlink data transmission due to the fact that the...
Some millimeter wavebands, such as 60 GHz, would probably be selected as the main operating frequencies of the next 5th generation wireless/mobile communication systems, for their obvious advantages of wider available transmission bandwidth and higher achievable transmission rate. In this paper, a novel structural design of microstrip antenna array working at the 60 GHz frequency band has been proposed...
The resistive random access memory (RRAM) technology is a promising candidate for the replacement of NAND FLASH at ultra-scaled nodes. In this work, the scalability of a 2-layer RRAM cross-point array architecture is explored towards the 10 nm node. Device-circuit co-design methodologies are employed to optimize the array architecture. The impact of sneak paths, IR drop along the wire interconnect...
In this work for the first time a simultaneous 1.5 GHz / 3.8 GHz dual band power amplifier (PA) with different operation modes for each frequency is presented. A dedicated matching network is employed to synthesize Class-AB impedance condition at lower bands and Class-J condition at upper bands. A low cost GaN-on-Si device with plastic package was used for demonstration. The measured results show...
This paper presents a design and implementation of a HyperTransport (HT) core in lattice SCM FPGA which can run at 800 MHz DDR link frequency. An effective approach is also proposed to solve the ordering problem caused by different virtual channels which exists not only in HT but also PCI-e. HT is a high performance, low latency I/O standard which can be used directly to connect with some general-purpose...
