1. Design an amplifier,incorporating a 2N3904 NPN bipolar transistor, which has a š¯›½ value of 300 as specified by the manufacturer. The amplifier should act as a bandpass filter with a lower cut-off frequency of 50Hz and upper cut-off frequency of 20kHz. The roll-off at both the lower and upper cut-off frequency should be a first order characteristic (20dB/decade). The amplifier should have a gain of 2dB in the passband.
2. The list of components that can be used:Resistors E12 seriesCapacitors E6 seriesNPN transistor 2N3904 (required)PNP transistor 2N3906Op-Amp LT1028Power supply 12 V voltage sourceInput signal Sinewave with an amplitude of 10mV
3. A bode plot theoretical response of the circuit and a simulation of the complete design on LtSpice. Write down any difference between the theoretical response and the simulation.
4. Report must have:
– Discuss your design, highlighting design choices that you have made, and the reasons forthose choices (30%)- Analyse your design, showing the theoretical performance. This analysis must include abode-plot of the expected frequency response (30%)- Include a simulation of your design in LTSpice (15%)- Incorporate a discussion highlighting any differences between your design and thesimulation, explaining why these differences arise (25%)Refer to the example report that I have given you.
