Thank you for your reply, due to that resistor is area consuming, I prefer a MOSFET configuration, is there any common way for this?

Thank you!
This classic configuration is good enough! Plz refer to

Dear all
I need to design a circuit which used to shift down a logic level from 1.8V to 0.9V.
I search in the google and ieeexplore, but all the references and papers are designed for level-up.
Due to this is a tiny structure, so that this structure maybe just mentioned as part of a whole...
Dear Everyone
I am trying to observe some output curve by Wavescan. When I use trace cursor, try to get the value of the curve, the coordinate on the left bottom cannot display normally (messy code). I use SSH and WIN32 to connect to the server to use Cadence. I suspected the problem was the...
Have you done the hand calculation? For your design, to achieve the 600Mhz UGB, the Gm of differential input stage should be at least 300uA/V, so plz check is that Gm1 lower than the 300uA/V. If it does, you can try to increase the bias current to increase the Gm1.
Hello, I am a newbie of IC. And these days, I really confuse about the "input impedance". According to TWO-PORT,
for a VCVS, we should open the output to calculate the input impedance, and for a VCCS, we should short the
output to calculate the input impedance. But for a OPAMP or OTA, should I...
