Design Considerations for an Isfet Multiplexer and Amplifier

Design conslderatlons for the multiplexing of pH-sensitive ISFETs are studied and discussed Expernnental results with an ordinary multiplex clrcult show transients of the order of several seconds if the output voltage of the applied amplifier 1s required wlthm an accuracy of 0 5 mV (corresponding to 0 01 pH unit) These transients appear to result from thermal mstablllty of the ISFETs during swi...

AN1106: Practical Current Feedback Amplifier Design Considerations

The current-feedback (CMF) amplifier is a fundamentally different approach to high-frequency gain blocks. Not just an input stage, it is a full amplifier topology. It has outstanding characteristics in several areas: very high slewrates, -3dB bandwidth which is almost constant with increasing circuit gain, and low high-frequency distortion. Almost all commercial CMF products offer these benefit...

Effective Design of a 3×4 Two Dimensional Distributed Amplifier Based on Gate Line Considerations

In this paper two dimensional wave propagation is used for power combining in drain nodes of a distributed amplifier (DA). The proposed two dimensional DA uses an electrical funnel to add the currents of drain nodes. The proposed structure is modified due to gate lines considerations. Total gain improvement is achieved by engineering the characteristic impedance of gate lines and also make appr...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
