Hi,
I am currently designing a folded cascode amplifier. I have designed the cascode transistors with Vov = 100mV. Vdd = 2.5 V. Vinput common mode = 1.25
i simulated the DC transfer curve for Vicm = 0 to 2.5. I got all the transistor in saturation from 1 to 1.8 V (constant slope). When when I simulated for output swing, upon giving differential input signals, my cascode leg transistors go into triode region. range of differential input voltage give is from +- 0.05
Please help me look at the direction to solve this problem.
Thanks
Ashwin
