Build the circuit as shown in the figure (You drew this circuit in Eagle CAD Lab 3). Make it work and try to figure out how it works. For your lab report, write a description on how the circuit works in your own words. Use a VCC of 5-10 volts. Use the BC337 in place of 2N2222A. Watch out for capacitor polarity if you are using an electrolytic.
- To learn how to connect different transistors as switching and amplifier circuits
- To measure voltage drops across the transistor circuits and to ensure Kirchoff's laws still apply
Observations1. Plot a graph of Vout vs Vin for the amplifier circuit
2. Maximum allowable collector current for both circuits are:
3. Minimum resistance necessary to ensure diode safety for the applied voltage is:
4: Obtain the specifications sheet for the transistor and note down max ...
Instructions for lab writeup: All lab reports are to be typed. All sketches, tables and graphs are to be made using software (i.e. not by hand). Each report is due one week from doing the lab. The outline for the first lab report is as follows:
- To understand how to use the prototyping board (breadboard), power supply and multimeter
- To assemble a simple circuit consisting of resistors in series and parallel configurations
- To verify Ohm's Law for ...
Eagle CAD is a powerful piece of software for anyone interested in electronics as a hobby or professionally. It features a beautiful schematic drawing engine and solid automated layout and PCB design modules. It can also, in conjunction with the POVRay raytracing program, produce 3d rendered images of finished boards as well.
We will be using Eagle to draw our schematics for this class for our lab assignments. It will be installed on the computers in 248, but feel free ...
