Its a transimpedance amplifier (Vi --> Id using the input stage, then Id--> Vo using the pmos cascode load). CMFB is SC. Load is 675 fF at each output.
Yuvan,
f1= f3dB = 642.19 KHz
f2 = 700 MHz
OK I will try that approach, Thanks.
Sudheer, I tried what you said, but doesn't work :|
Any suggestions welcome.
Hi, thanks Dominik & Yuvan.
Dominik, I am allowed to use the same configuration without using gain boosted cascodes (Don't you think they'll introduce extra poles from the tiny amplifiers?)
I will look into these papers.
I am trying to increase I (tail current) and W/L by twice of the input...
I am designing a PMOS input folded cascode OTA, specs are VDD = 1.2 V, current limit = 1mA, Gain>=60dB, Output Swing = 1 V (differential), UGBW >= 800 MHz.
V,CM (output) =0.6 V. Can anybody suggest how do I go about improving the UGBW from 400 MHz(present) to 800 MHz ?
Please let me know if I...
