The simulation results on the four basic characteristics of the BJT amplifier which are emitter current, voltage gain, input impedance, and output impedance were observed Draw Common Emitter Transistor Characteristics Using LTspice May 10, 2020 May 10, 2020 by Admin Aarvis.in Initially, before going into the details of common emitter transistor characteristics, we will check the basics first. Fill in the rest of the values for that source. Although we can compute and plot it, … A common emitter Bipolar Junction Transistor (BJT) amplifier has been constructed and simulated by a free LTSpice simulation tool. To demonstrate the capability of the tool, a basic single stage common emitter Bipolar Junction Transistor (BJT) amplifier is constructed and simulated by using the LTSpice. I have to create input bipolar transistor characteristic (Ib/Ube), but i don't know how to do it. The BJT can be of npn type of pnp type based on the configuration of the regions. So, enter the values for the below parameters. The most important characteristic of the BJT is the plot of the collector current, I C, versus the collector-emitter voltage,V CE, for various values of the base current, I B as shown on the circuit on the right. This post tells about characteristics of power BJT. Now, Click OK .Then we will get the input characteristic. Now click on “OK” button and click “Run”. LTSpice As A Curve Tracer: BJT I-V Characteristics * * Circuit Description * VCE C 0 0V. In common emitter configuration, emitter is common to both input and output. If you are considering starting LTSpice, check out this post first: An Introduction to LTSpice This post is a continuation of my LTSpice topics and may be confusing to first users. While Unipolar transistor i.e. What voltages and currents would you apply? To set that up in LTspice, right-click in the schematic window and select Edit Simulation Cmd. Then the screen will be divided in to  two parts (circuit & graphic part) as seen in the below screen shot. In our case, the base is a low-doped p-type semiconductor, which increases the resistance of p-type material. jarlos,Think how you would do this if you had that transistor and some test equipment on a bench.

Click OK and we will get the output characteristic. The built-in transistors can be found in the file lib/cmp/standard.bjt in the LTSpice installation directory.. You can copy one entry as a single SPICE directive into your circuit, rename it, and change the Bf parameter: (To select a custom transistor model for a component, use Ctrl+right click.) Learn how your comment data is processed. Output characteristics can be plotted on a graph between output voltage (Vce)  and output current (Ic) for a constant base current(Ib).The circuit diagram for plotting Output characteristics is shown below. In the below figure , x axis is “Vce” having value is vary from 0 to 10 v. For plotting output characteristic measure the “Ic” and plot it on y axis. IB 0 N001 10µ * device under test. “Vce” is the collector emitter voltage applied between collector and emitter. “R1” is the input resistance having a value of 620 ohm and “R2” is the output resistance  having a value of 420 ohm. For the first source, choose the one you want to be on the X or horizontal axis of your plots. Commentary, Explanations and Examples (This section is currently blank. 2. Subject of the new topic: Hello. Here, the emitter terminal is common to both input and output. To change β F, type in “BF = 200” after “NPN”, as shown below. This plots the large-signal gain of the circuit shown on the right. You can see the symbol of an NPN transistor in the below image. These three types of configurations respond differently to the input signal applied to the circuit because of the static characteristics of the BJT.
