In summary, luna.spell is seeking help with designing a common emitter amplifier with specific parameters. They also need assistance with calculating input and output impedances, obtaining frequency response, and finding band width, midband gain, and cut-off frequency. They are struggling with this coursework and have not been able to find helpful resources.

hey my name is luna
i need a help i have got work to do is how to design a common emitter amplifier with emitter resister and emitter bypass capacitor for the following:
voltage gain= 70
lower cut off frequency = 135 Hz
Take RL as 10k AND quiescent operating points , Vce = 6V and Ic = 2 mA

simulate the designed circuit using any ECAD tool ( ORCAD)
1) Calculate the input and output impedances of the amplifier.
2) Obtain its frequency response and find out its band width, midband gain and cut-off frequency...

i hope anyone can help me how to get those coz am alone in doing this course work :( i hope you would help me as soon as you can
Thank you very much

Welcome to PF, luna.spell

For course and homework questions, we like to see the student make an attempt at solving the problem before giving out help. Please provide any thoughts you have on how to go about this.

Also, we have a homework question area where homework questions should be posted.

FAQ: Need help in analogue electronics

What is analogue electronics?

Analogue electronics is a branch of electronics that deals with the continuous variation of signals, as opposed to digital electronics which deals with discrete values. This includes the study and design of circuits that process and transmit signals such as audio, video, and radio signals.

Why is analogue electronics important?

Analogue electronics is important because it is used in a wide range of applications, including communication systems, audio and video equipment, medical devices, and many more. It also serves as the foundation for digital electronics, making it essential in the development of modern technology.

What are some common components used in analogue electronics?

Some common components used in analogue electronics include resistors, capacitors, inductors, diodes, transistors, and operational amplifiers. These components are used to manipulate and amplify analogue signals in various circuits.

What are some challenges in designing analogue circuits?

One of the main challenges in designing analogue circuits is dealing with noise and interference. Analogue signals are susceptible to noise, which can disrupt the accuracy and quality of the signal. Another challenge is ensuring stability and reliability in the circuit, as small changes in component values can greatly affect the performance of the circuit.

How can I improve my skills in analogue electronics?

To improve your skills in analogue electronics, it is important to have a strong foundation in basic circuit analysis and design principles. You can also practice by designing and building your own circuits, and learning from experienced engineers or through online resources and tutorials. Hands-on experience and continuous learning are key to mastering analogue electronics.
