Class A amplifier Project As part of an electronic system a common emitter class A amplifier is required to be designed and simulated using Pspice. This amplifier uses the BJT Q2N2222 that can be biased using one power supply of 18 volts DC. This amplifier feeds another stage with input impedance of 17k ohms. The amplifier should amplify a signal with frequencies between 210Hz and 50kHz. At the medium frequencies range the output signal is required to be 95 times larger than the input signal which is 7mVrms AC. The collector current at operating point ICq is of 10 mA. Nominal preferred values for components should be used and all calculations for component values should be shown. Known values are here as shown: Vin = 7mV RMS Vcc = 18v Lower cut-off frequency = 210Hz Higher cut-off frequency = 50kHz Output impedence (ROUT) = 17k ohms Vout / Vin = 95 Collector current Icq = 10mA The screenshot attached is roughly what the circuit should look like. A screenshot of the schematic and the schematic itself are attached to the file. What I need is somebody who can calculate the correct values of the components shown on the schematic send send me them so I can modify the circuit to give the desired output. Any questions please contact me, thanks.
