Can anyone please provide materials regarding the calculation of the transfer function of two stage and telescopic op amps...........
Thank you in advance.
 

For the 2 stage opamp, refer to Allen&Holberg, it has very detailed explanations.
 

for 1 pole op: Vo(s)/Vi(s)=A0/(s/ω0+1)
for 2 pole op: Vo(s)/Vi(s)=A0/[(s/ω0+1)*(s/ω1+1)]
u will need to find ω0 & ω1 from ur ckt.
 

a good designed op can been looked as a 1pole op.
 

Refer Cmos Analog Circuit Design by Allen & Holberg u will find in chapter 6. Also if u need any further help rearding it u can look into the Bezad Razavi or Meyer book.I hope it will help u to solve ur problem.
 

Even in John Martin book u find explanation about the opamp.
 

behavior model, ideal opamp looks like a 1 pole amp, Av/1+jf/fp

details pls look at any of the analog design books
