    The MOSFET represented a radically new technology, the adoption of which would have required spurning the progress that Bell had made with the bipolar junction transistor (BJT). The MOSFET was also initially slower and less reliable than the BJT. However, the MOSFET generated significant interest at RCA Laboratories and Fairchild Semiconductor.

The chip designs are slightly different and the fabrication process is different but the transistor characteristics The MOSFET circuit technology has dramatically changed over the last three decades. Starting with a ten-micron pMOS process with an aluminum gate and a single metallization layer around 1970, the technology has evolved into a tenth-micron self-aligned-gate CMOS process with up to five metallization levels.

    Short Tutorial on PSpice

    Short Tutorial on PSpice. Spice is a program developed by the EE Department at the University of California at Berkeley for computer simulation of analog circuits. In its original form you tell Spice what elements are in the circuit (resistors, capacitors, etc.), and then enter the circuit diagram as an ASCII file showing what nodes each element is connected to. The switch model allows an almost ideal switch to be described in SPICE. The switch is not quite ideal, in that the resistance can not change from 0 to infinity, but must always have a finite positive value. By proper selection of the on and off resistances, they can be effectively zero and infinity in comparison to other circuit elements.

    I've been trying to learn how to use LTspice, and I'm attempting to create a model for a pFET I've been using/will use on a real board.

    LTspice Tutorial 4 explained that there are 2 different types of SPICE model: those defined by the simple .MODEL statement and those defined by the more complex .SUBCKT statement. The .MODEL statement defines simple components such as diodes, transistors, MOSFETs etc with a list of predefined characteristics given to us by the writers of SPICE programs. Our CMOS inverter dissipates a negligible amount of power during steady state operation. Power dissipation only occurs during switching and is very low. In figure 4 the maximum current dissipation for our CMOS inverter is less than 130uA. Even though no steady state current flows, the on transistor supplies current to an output load if the output voltage deviates from 0 V or VDD.
