摘要：Metal Oxide Semiconductor Field Effect Transistor (MOSFET) is a type of Field Effect Transistor, which acts as a voltage-controlled current device. It operates by controlling the width of the channel that lies between drain and source terminal. Depending upon the width of the channel along which the charge flows the operating region of the transistor is defined. These operating regions are cut region, triode region and saturation region. This paper presents the analysis and evaluation of IRF150 n-channel E-MOSFET in OrCAD Capture. The analysis includes the characteristics curve, voltage transfer function and power consumption of MOSFET. The evaluations of the small signal characteristics, analog and digital frequency response and maximum frequency of the MOSFET are also presented. Through the evaluation, the minimum threshold voltage required to turn on the transistor IRF150 is found to be 3V. The MOSFET exhibits switching logic threshold voltage of 2.872V. The resulting low noise margin and high noise margin are approximately +11.928% and -16.316% respectively. The power consumed with low input voltage is 126.020 nW and24.992mW for high input voltage. With the corner frequency of 55.857 KHz and slope of 18.975 dB/Decade the evaluated MOSFET circuit behaves like a low pass filter.
