This paper presents the design of an analog CMOS Gilbert cell Mixer for RF Receiver front end application. Input RF frequency of the mixer is 2.4GHz and operated at 1.8V power supply. The schematic has been implemented using UMC-180nm CMOS technology and simulated on spectre-RF simulator of Cadence. The input RF and LO frequency of the proposed mixer is 2.4GHz and 2.25GHz respectively, resulting in...
Events give important information about the behavior of a system in a summarized form. In the past, events have played an important role in breaking the functional requirements of the system in the ??event partitioning approach??. Our previous work has shown that events can be a starting point in object-oriented analysis of requirements. Every event triggers a use case in the system, hence should...
Current petascale systems have tens of thousands of hardware components and complex system software stacks, which increase the probability of faults occurring during the lifetime of a process. Checkpointing has been a popular method of providing fault tolerance in high-end systems. While considerable research has been done to optimize checkpointing, in practice the method still involves a high-cost...
Nowadays cellular systems operate with frequency reuse one, where adjacent cells use the same frequency band. Use equipments (UEs) located at cell edge are mostly affected by the resulting co-channel interference. In addition, cell edge UEs suffer from their weak carrier signal strength. This paper proposes a new method to increase the performance of cell edge UEs by means of information exchange...
Summary form only given. Microsystems implemented on chips or SoCs provide new capabilities and alternatives not easily available to architects in the past, via ISA extensions, additional data-path elements, SIMD arrays and their short vector extensions, multigrain coprocessing etc. We can, given enough design resources, build such machines. Evidence of various combinations of architectural archetypes...
