MOSFET Circuits - Level 3 Spice with Constant Output Conductance versus Drain-Source Volts - ETA Effect

POST Circuit - Pspice Schematics Common-Source Gain Stage This Simulator Version is Based on the ETA Effect (a function of vgs, in this case) in Pre-Sat Parameter fs is from the XJ effect. VTo is the threshold voltage at vds = 0, and VT is, for this simulator, for a value of vds in Pre-Sat. Voltage Vdsat is variable sat voltage at a given vds. Vdsatp is the variable sat voltage at Sat-Post Sat. Pre-Sat Drain Current LabVIEW Simulation - In vds Saturation Asm is the ratio of this simulator and Level 3 Standard at VDsat. This precision form for Lp is discussed in the following (Eq. 6.2.1): (Operation and Modeling of the MOS Transistor, 2nd Edition, Yannis Tsividis, McGraw-Hill) LabVIEW for both Simulators Read Pspice Schematics DC Sweep of POST Circuit

MOSFET Circuits - Common-Source Amplifier Stage with Resistor Load - Part I

Image
The projects in this blog utilize the Blog LTspice equivalent Level 3 Spice, with constant output conductance over the full range of drain source voltage. The derivation is periodically considered. NMOS Amplifier Stage - LTspice Blog Level 3 Review. MathCAD Compare Post Sat Region Modulators Parameters m and  lc. Match Id - vds slope, pre-sat and sat, at vds = VDsat Id and Id3 (standard) converge as vds approaches infinity. Equate lc functions. Solve for parameter m, for a given VDsat (Vg) Find vd for gate width W = 10 um, and then iD. LabVIEW Iteration Function. Iterate to set sum of currents at vd node = zero (approximately). At solution. Function f = iD - ir. LabVIEW Circuit - Gate vg is applied with Global Variable. Iteration variable vd is assigned to Global Variable here. Iteration Program This program indicates the convergence rate for an init vd = 1 V and vg = -1.58 V. The values are init followed by vd outputs for index = 0,1,2.
