Operating as a unity-gain follower, DC gain accuracy is 0.002% typical and acquisition time is as low as 6 µs to 0.01%. Electrical and Computer Engineering . All circuits must contain a zero node. pSPICE is a proprietary circuit simulator provided by OrCAD. Or if you have questions, email kirsch@learnorcado. As shown above, bias parameters can be displayed directly on the schematic by adding a small signal source and collector load. If we need a graphical output, PSpice can transfer its data to the Probe program for graphing purposes. Select the library (*.lib) path by "Browse…" labeled with numbers or letters. What is wrong with this PSpice simulation? All power device models are grouped in dedicated library files, according to their voltage class and product technology. Pspice is now a component of the OrCAD Product Family This <letter>is followed by a unique instance name and then (in order) the nodes associated with + and - voltage and the value of the associated parameter (R, L, or C). Implementing a BJT small signal model in PSpice, as shown in Fig. www.orcad.co.uk Here we explore the various simulation types with Cadence OrCAD PSpice AD The program will run and will prompt the user to enter the name of the .CIR file they wish to compile at the prompt.
