Hi,
can somebody please tell me, the precedure of measuring slew rate of a diff op amp in cadence?
 

use the opamp as a comparator and then use the calculator in analog environment to find the slope of the output to find the slew rate....
 

hi, im not sure about the input amplitude, does it have to be as large as possible?
 

ya..... but it is necessary that it should be the largest... it is something like beyond a particular drive the output slope would not increase... simulating with the highest drive is a better idea....
 

give input step and measure the output slope.
 

the step should be the highest full swing amplitude , and the output shoud be loaded with the load cap , then u measure the output slope

khouly
