Hello,
I have a two stage single output opamp. I want to create inverting and noninverting amplifiers and other circuits using the op amp.
How should the choose the resistance values that are connected at the input and feedback?
Opamp specs:
gain 75 dB
phase margin 55 degrees
unity gain bandwidth 750 MHz
slew rate 4.2 MV/s
VDD 1 V
dynamic range 0.32 - 0.7 V
current (diff. amp.) 3 uA
current (cs. amp.) 22 uA
feedback capacitor 500 fF

A schematic of the entire circuit with values and part numbers for the IC's is essential for any answer.

A fancy schematic is not nesesary. Do a hand drawn sketch and take a good photo.

Hello,
I am using low threshold voltage transistors, primarily because the technology I am using provides regular MOS with high threshold voltage.
Eg. for 65nm devices, the regular transistors have threshold as high as 0.4 V while the VDD can be 1 - 1.2 V.
