Multimode multiband connectivity has become a defacto requirement for smartphones with 3G WCDMA/4G LTE applications. In this research, a two-stage multimode multiband (MMMB) power amplifier (PA) with multiple gated transistor (MGTR) and configurable tapped transformer is designed and analysed in view of enhancing the efficiency in low power mode. The designed MMMB PA offers a 900MHz of operating bandwidth...
The popular use of biomedical implants has been going on in numerous applications that include the use of pacemakers and emerging retina prostheses, together with brain-computer interfaces. Other popular uses include drug delivery and smart orthopaedic implants. The avoidance of batteries or piercing wirings has made the wireless powering of these implantable devices highly attractive. In this paper,...
Dynamic Thermal Management (DTM) emerged as a solution to address the reliability challenges with thermal hotspots and unbalanced temperatures. DTM efficiency is highly affected by the accuracy of the temperature information presented to the DTM manager. This work aims to investigate the effect of inaccuracy caused by the deep sub-micron (DSM) noise during the transmission of temperature information...
With increasing consumer demand for wireless devices to support multiple air standards and applications, there have been increased trends for implementation multimode multiband (MMMB) devices in the RF front-end of wireless handsets. This paper presents a design of multiband band pass filter (BPF) in 130nm standard CMOS technology that can operates in 12 different LTE bands (band 1, 2, 3, 4, 5, 8,...
With increasing consumer demand for wireless devices to support multiple air standards and applications, there have been increased trends for the implementation of multiband (MB) devices in the RF front-end of the wireless handsets. This paper presents the design of multiband low noise amplifier (LNA) in the 130nm Silterra CMOS technology. The proposed LNA operates in five major LTE bands (band 1,...
In this paper, a high-speed low-power full adder design using multiplexer based pass transistor logic featuring full-swing output is proposed. The adder is designed and simulated using the industry standard 130 nm CMOS technology, at a supply voltage of 1.2 V. The obtained Power Delay Product (PDP) of its critical path is 29×10−18 J and its power consumption is 2.01μW. The proposed full adder is also...

In the contemporary and future MOSFETs, NBTI/PBTI-related charge trapping in the presence of underlying statistical variability gives rise to statistical degradation of the coresponding electrical characteristics and figures of merit. We present a framework that integrates the statistical aspect of the NBTI/PBTI degradation, obtained from large-scale 3D ‘atomistic’ device simulations, into statistical...
