Hello, I need help trying to solve this problem in example 2.26 of my Microelectronics Book
" An internally compensated omp amp is specified to have an open loop dc gain of 106dB and a unity gain bandwidth of 3MHz.Find Fb."
Oringally I thought that I could find fb since
ft=wt/(2*Pi)
fb=wb/(2*Pi)
and since wt=open loop dc gain*wb
I thought I could find fb by doing
ft/open loop dc gain=fb
however it turns out the answer is 15Hz
