We must avoid the region where V GS > 0, and where V DSĮxceeds the manufacturer's limit, and we must take care that the product: I D Where the drain current I D is essentially constant, the so-called constant current The optimum region for the JFET is in the region Choosing the Operating Pointįirst of all, we want the amplifier to work in a linear region to minimise the amount There are a number of factors to consider when picking the Now that we have the characteristic I-V plot for the device, we can choose a DC operating Successive curves have a gate-source step voltage of -0.5V The DC Operating Point and Load Line The topmost curve is for a gate-source voltage of 0V V GS plot for the 2N3819 n-channelįigure 1a - The Spice I D vs. Shown below is the transfer characteristic I D vs. J1 as a function of VDD (the drain voltage) and VG (the gate voltage) as these To the schematic above it instructs pSpice to plot the drain current in Fortunately, it is fairly easy to convert a schematic diagram The schematic is just for the convenience of a humanĭesigner. Typical device will respond, and not a measurement as such. It's important to remember, this is a prediction of how a Out I-V characteristics of the device J1 corresponding to pSpice's The circuit below entered into pSpice will let us plot The results are only as good as the model used

Proteus Professional is a Shareware software in the category Education developed by Labcenter Electronics. In summary, Proteus 7.0 is the program to use when you want to simulate the interaction between software running on a microcontroller and any analog or digital electronic device connected to it. Proteus VSM comes with extensive debugging features, including breakpoints, single stepping and variable display for a neat design prior to hardware prototyping. One of the main components of Proteus 7.0 is the Circuit Simulation - a product that uses a SPICE3f5 analogue simulator kernel combined with an event-driven digital simulator that allow users to utilize any SPICE model by any manufacturer. This program allows users to interact with the design using on-screen indicators and/or LED and LCD displays and, if attached to the PC, switches and buttons. This is the perfect tool for engineers to test their microcontroller designs before constructing a physical prototype in real time. Proteus is a Virtual System Modelling (VSM) that combines circuit simulation, animated components and microprocessor models to co-simulate the complete microcontroller based designs.
