Hello everyone. Could someone please help me with the following problem?
I am given the circuit in the following image:
All the BJT transistors, Q1-Q5 are contained within a single CA3096 chip and the output buffer stage is simply a 741 op-amp configured in its unity-gain mode.
It is assumed that:
1) \(_{}V\)BE-on = 0.7 V for all transistors
2) The 741 is an ideal op-amp
3) The dd value of \(_{}V\)C5 = 0 V
Given the above specs, I know that the transfer function is
A(s) =\(\frac{wt}{s}\)
and \(_{w}\)t = \(\frac{gm}{Cpi + Cmu}\)
My question is, do I have the correct approach in obtaining the transfer function? That I need to find for Cpi + Cmu in order to find wt? Or is there another method in doing this?
Also, does anyone know how I would find the slew rate (SR) for this circuit? I know that SR = \(\frac{voltage change}{time change}\)
But how would I find Δt?
Any help is greatly greatly appreciated! Thank you.
