Plt.In this projectiot123 tutorial we will Learn the Download Proteus Library of Components.The simulation model of an electronic component contains the information about the input and output relationship of the electronic component in the form of the mathematical equation. # some output so that we know what the smu is doing # do a voltage sweep for every base current we defined # define sweep parameters for the collector base voltage # define base currents we want to run the sweep onĬurrent_steps = # define the initial parameters for the channel # define variables we store the measurement in # set the measurement speed to med (so we can sweep really faster than in normal mode) # setup the operation mode and what will be shown at the display Writer = csv.writer(csvfile, delimiter=' ', lineterminator='\n') Time_for_name = ().strftime("%Y_%m_%d_%H%M%S")įilename_csv = 'npn_common_base' + time_for_name +'.csv'įilename_pdf = 'npn_common_base' + time_for_name +'.pdf' # Create unique filenames for saving the data # enable the debug output (= lots of print commands)
""" EXAMPLE: common base characteristic of an NPN Transistor """ Connect the Hi of channel A to one of outside leads of the transistor, the Hi of channel B to the other outside lead of the transistor and the common ground to the base at the middle lead.ĭownload the Python script npn_common_base.py and the Python library Keithley 2600 Python library and save them in your bipolar-transistor directory. The base is the middle lead of the transistor. Although the currents are the same at the input and output, the voltage at the output can be much larger than at the input. The collector current is almost equal to the emitter current. Most of the electrons injected into the base diffuse across it and are collected at the reverse biased collector-base junction. The current between the collector an base is then plotted as a function of collector-base voltage. The base is grounded and a current is passed from the emitter to the base so that the emitter-base junction is forward biased (\(I_E\) is negative for an NPN transistor). We will start with a common base configuration. This page describes how to use a Keithley 2600 Series Sourcemeter to measure the characteristics of an NPN bipolar transistor.
