A Computer Program for Small Signal HEMT or GaAsFET Model in Fiber Optic Receiver Circuit
Abstract: A fully automated program to determine the GaAsFET/HEMT small signal models for use in optical communication front end amplifier circuit is given. The program requires only initial values of parameters which are commonly available in literature determined by experimental procedures and two port analysis theory using analytical formulae. The program was tested by giving starting values within minimum and maximum ranges of parameters obtained by available manufacturer’s data and theoretical …

Bio Impedance Technology and Measurement Using Sensitized Garments- as Review
Abstract: Bio impedance has the potential for playing an important role in this scope, especially because of its relatively reliable, electrode-based sensing principle and its broad range of applications. On the other hand, there are also some challenges for the successful exploitation of this technique in a wearable device, like the reduction of power consumption and the control and optimization of the measurement for a specific application using a wearable electrode …

Spin Devices Based Area Efficient 5-Bit High Speed ADC
Abstract: This paper uses current induced domain wall motion in a magnetic stripe and pre-charge sense amplifiers (PCSA) to design a high-speed comparator of a magnetic flash ADC. Current-induced domain-wall (DW) motion is a prominent switching mechanism promising, low power high-density and high-speed circuits. Domain-wall motion in a magnetic stripe basedmagnetic flash ADC (Analog to Digital Converter) is area efficient (4.84μm2 ) and faster compared to other ADCs. Our proposed 5-bit …

MATLAB Simulation Processes on Pneumatic Force-Balance Transmitter
Abstract: A pneumatic force balance transmitter in which an input force proportional to the fluid flow rate being measured is applied to a force bar pivoted about a transverse axis to produce a torque. A rebalance torque is applied to the bar by means of a negative feedback loop, in which a pneumatic detector functions to sense any change in bar position, the detector output being amplified to produce a pneumatic …

Biosensor: Recent Advances and Potential in Biomedical Applications
Abstract: A powerful and innovative device used for detection of biological elements is referred as “biosensor”. It gives useful information whether or not the analyte is present and at what level is transduced into an electrical signal that can be amplified, displaced and analyzed. In medicine, biosensor can be used to measure glucose [1], diagnosis pathogenic/cancer disease [2], biomedicine and drug delivery applications [3].
