BJT Audio Amplifier Project This semester's project is simply to replicate the CircuitLab audio amplifier circuit seen here: https://www.circuitlab.com/circuit/6syafk/bjt-audio-amplifier/ The project will be in the same format as your lab reports

and done in the same groups/ pairs as the labs. The original circuit uses the 2N3904 NPN BJT, however, you may double-click the BJT in CircuitLab and select another BJT. Please also take note of the BJT's beta-value labeled B_F. My Device Models Refresh C name: Q1 Part#: 2N3904 No device models found.

For example, if Student A has N-number NXXXXXXX3 and Student B has N-number NXXXXXXX6, the required voltage gain A, will be 63. If the gain calculated is less than 50 (eg. 29), add 50 to it (>79). You will be required to adjust circuit parameters such as R₁, R₂, Rc and V, to ensure that the output signal swing and DC bias point do not cause the BJT to enter the saturation region while still achieving the required voltage gain. The first part of the project is to perform the DC and small-signal analysis of the circuit by hand. Similar to the original project, DC analysis, Input DC Sweep, Time Domain Simulation and Frequency Domain Simulation should then be performed. • Please include waveforms for the DC Sweep, Time Domain and Frequency Domain Simulations in your report. • Also, compare your hand calculated DC voltage and current values to those observed in CircuitLab. The maximum value in the Frequency Domain Simulation (Bode Plot) should be the decibel value corresponding to a value approximately equal to the required voltage gain, A. • Please also include a link to your CircuitLab project in your report and make the project either unlisted or public in CircuitLab so that others may access it.
