For a second order system with the transfer function: T=1/(s²+sω/Q+ω²), how can I get the conclusion that when Q»5, the 3db bandwidth is approximately ω/Q?
Can anybody give me some hints on making this derivation?
I try to design a two stage opamp according to the following picture:
The Rz I used is 5.6k. I tried to used a MOSFET in linear region to take the place of Rz to save some area. I used Hspice to test that when MOSFET is used the Hole and Zero are in the same place as resistor is used. But...
As the following :
Simulate your design under different corners and temperatures. Your PVT
simulation must include the corners below:
Process: tt, ss, ff
Voltage: Vdd =2.7
Temperature = -24
I am a beginner, so any master can tell me what is the "corners" above stand for?
