Design an operational amplifier. Your operational amplifier a) Should consists of at least 4-stages (current source should also be designed, ideal current source usage is not alllowed), b) should have a voltage gain 2 60dB, c) Unity gain frequency 2 30MHz. Your report should contain; a) Op-amp design, b) DC & AC analysis and transfer function of each and every stage, c) Input and output resistance calculation for common and differential mode inputs, d) DC, time domain and frequency domain analysis using PSpice (or Proteus) e) Find the lower and upper cutoff frequencies (Explain how you find it, what can be done to extend the bandwidth) f) Phase difference between input and output signals. (phase difference, effect of the difference on circuit behavior, possible techniques to reduce it) g) Show the slew rate for your transistor (explain the slew-rate definition and find the slew-rate for your Op-amp) You can use MoS and BJT type transistors or both.
