... of ( 12. 19) is equal to ( 12. 22) Equating this result to unity and squaring both sides, we write ( 12. 23) ã Where  u denotes the unity-gain bandwidth. It follows that ( 12. 24) ( 12. 25) ( 12. 26) which ... the closed-loop gain. Since ( 12. 50) ( 12. 51) ( 12. 52) we have: ( 12. 53) and hence ( 12. 54) an expected result. Example 12. 15 Determine the closed-loop gain of the...
