Pressure swing adsorption technologyEdit. The operating principle of a nitrogen generator utilizing the adsorption technology is based upon the dependence of the adsorption rates featured by various gas mixture components upon pressure and temperature factors. Among nitrogen adsorption plants of various types, pressure swing adsorption (PSA)...

The purity of the nitrogen from PSA and membrane systems is a function of its throughput. For example, assume a PSA is designed to produce 99% nitrogen at a certain design flow rate. When the PSA is only producing onethird of this flow rate, the nitrogen purity is higher than 99%.

Establishing the correct operating point requires the selection of bias resistors and load resistors to provide the appropriate input current and collector voltage conditions. The correct biasing point for a bipolar transistor, either NPN or PNP, generally lies somewhere between the two extremes of operation with respect to it being either "fullyON" or "fullyOFF" along its DC load line.

Tunnel diode is a highly doped semiconductor device and is used mainly for low voltage high frequency switching applications. It works on the principle of Tunneling effect. It is also called as Esaki diode named after Leo Esaki, who in 1973 received the Nobel Prize in Physics for discovering the electron tunneling effect used in these diodes.
