Solution:

An opamp operates as a unity gain butter with 3VPP square wave input. If opamp is ideal with slew rate 0.5 V/ microseconds, find the maximum frequency of operation.

 slew rate =2×π×f×v

where,

f= The highest signal frequency, H2

V= The maximum peak voltage of the signal.

0.5v/μs=2×π×f×1.50.5×10+6=9.42 FF=53078.55H2
