This paper discusses on the differential LNA design on Pseudomorphic High-electron-mobility transistor (pHEMT) based technology for wireless application, and the standard 1μm pHEMT is implemented throughout the design. The LNA design has been completed with two stages, with the purpose of successfully enhance the gain and noise performance. The proposed LNA design has the functionality of application...
There has been a paradigm shift in the modern teaching and learning method from face-to-face to blended learning style. However, most of the lecturers having difficulty in determining whether the blended learning style can be used as one of the approach to increase the student understanding on the engineering subject. Aiming to explore the effectiveness of blended learning model in engineering subjects,...
This paper present design and simulation of differential low noise amplifier that utilized inductively degenerated common-source (CS) open drain cascode topology. The operating frequency for the design was at 2.4GHz for IEEE 802.11b standard. The LNA has been implemented in RF 0.13um CMOS process. Power constraint noise optimization method has been used to obtain the optimized width of the transistor...
Kinetics of E'centers and threshold voltage shift, (ΔVth) of High-K Metal Gate Stacks has been comprehensively studied using two - stage Negative Bias Temperature Instability (NBTI) model. To effectively study the kinetics of E' centers, the two stage model was simulated with stage one only and then simulated in both stages. The evolution of trap kinetics was further investigated by varying parametric...
A 130-nm CMOS low-noise amplifier (LNA) for WCDMA applications is presented. The circuit adopts an inductively degenerated cascode topology. A detailed methodology using power constraint noise optimization (PCNO) method that leads to an optimum width of the LNA is presented. A theoretical noise figure optimization using fixed power was used as a design optimization guide. This inductively degenerated...
Virtual Reality (VR) are three dimensional, computer generated simulated environments that occur in realtime as manipulated by the user. VR technologies are promising tools for learning. The current demand to reduce the time and cost involved in doing laboratory experiments is to turn to new and emerging technologies such as VR technologies. This paper discusses a preliminary study conducted for a...
This paper presents the design for Low Noise Amplifier (LNA) using Silterra 0.18Mu technology and it based on W-CDMA standard application. The LNA function is to amplify extremely low noise signal without adding noise and also preserving required signal to noise ratio of the system at extremely low power level. Cadence design tool is used to optimize the simulation performance based on resistor and...
This paper is focusing on optimizing harmonic content in Sinusoidal Pulse Width Modulation (SPWM) design. This SPWM is designed using VHDL and implemented on ALTERA (DE2-70 board). SPWM output is generated by intersection between sine signal and triangle signal. Sine signal is the reference waveform and triangle waveform is the carrier waveform. When value sine signal is large than triangle signal,...
Amorphous carbon (a-C) thin films were deposited on quartz substrate at various temperatures with thermal chemical vapor deposition (CVD) technique using methane gas as precursor. The deposited a-C thin films were characterized by Current Voltage (I-V) Measurement and UV-VIS-NIR Spectrophotometer. In this experiment, the pyrolysis process was successful to analyse the electrical and optical properties...
The purpose of this project is to explore the techniques in developing the low voltage CMOS analog building blocks such as operational amplifiers. The main objective of this project is to design the low voltage single supply CMOS operational amplifiers for zero cross detector application. Circuits were aimed to operate standard supply voltage (3V). Achievement of high gain around 80 dB and 45 degree...
