Opportunistic spectrum access (OSA) in a decentralized network is a challenging problem since each unlicensed user (i.e. cognitive radio (CR)) needs to characterize frequency bands as per the occupancy statistics of multiple ...

Branch-line coupler and phase shifter are widely used passive components in RF and microwave communication systems. The designing of circuits operating at multi-band frequencies has the advantage of both compact size and ...

This thesis work provides theoretical analysis of an optical distribution network (ODN) that integrates mobile backhaul network with already existing passive optical network (PON). The need to reduce the cost of laying ...

Non Volatile Memories (NVM’s) are an integral part of every System-on-Chip (SoC) for retaining the data when power goes off. Phase change memory (PCM) is type of NVM and exhibits significant advantages over existing NVM ...

This thesis work proposes analysis and simulation of 5G multi-carrier transmission schemes based on generalized frequency division multiplexing (GFDM) along with existing optical orthogonal frequency division multiplexing ...

Audio applications necessitate precise data conversion from analog to digital domain. This high resolution conversion can be achieved by using Sigma-Delta architecture, which operates at oversampling rate and exhibits ...

Moving towards deep-submicron technologies, packaging density of ICs is increasing and thus the number of storage elements is also increasing on an IC. Any data corruption in these storage elements leads to huge amount of ...

The reduction in the device dimensions, the increasing switching activity and the high power consumption in the IC design cause large currents to flow in a Power Distribution network (PDN). The switching currents cause the ...

Low Dropout Regulators (LDOs) are extensively used in many applications ranging from high power system to the portable application like mobile phones, PDAs and notebooks. These portable applications demand high power ...
