Hi everyone,
For the lab final project we are required to design a impedance matching circuitry. By the way, the project comes from laboratory of analog electronics course. In this project we will design a circuit which is connected between two adjacent blocks and dynamically matches the input and output impedance of these individual blocks. I have uploaded diagram.
Requirements:
1) The designed circuit shouldn’t disturb the gain, i.e. A=1.
2) The circuit should match the impedance between 30Ω and 200Ω.
3) The circuit gain must vary in a maximum of 0.05, i.e. A=1±0.05.
4) The circuit should be capable of retaining these specifications between frequencies of 1MHz to 5MHz.
my idea:
As we have learned amplifiers for unity gain common collector amplifier should be used for matching impedance.
We have learned how to match a single impedance. But we have not learned how to match dynamic one. i.e. when input impedance increases or decreases our matching block should automatically match that impedance
The deadline is 2 days after. Please give your suggestions according to the course content that i wrote below. Because there may be several ways of doing this project. Thanks in advance for your suggestions. You can call me rami
General Course Content:
MOSFET and BJT Amplifiers
High and Low Frequency response of amplifiers
Feedback and topologies.
