Design a low-pass filter (LPF) with the following specifications:
Maximum attenuation in the passband region: 2.2 dB (monotonic)
Minimum attenuation in the stopband region: 30 dB (rippled)
Stopband region: w > 5000 rad/sec
Passband region: w < 3000 rad/sec
Maximum gain: 1
Tasks:
Sketch the gain curve for the obtained transfer function using MATLAB.
Realize the transfer function as a 1-ohm resistance terminated lossless ladder network (LC).
Realize the transfer function as a multi-amplifier RC network.
Verify the network using SPICE (obtain the gain curve and compare it with the one obtained by MATLAB).
Realize the transfer function as an OTA-C network.
Verify the designed passive circuit in the laboratory.
