... of ( 12. 19) is equal to ( 12. 22) Equating this result to unity and squaring both sides, we write ( 12. 23) • Where  u denotes the unity-gain bandwidth. It follows that ( 12. 24) ( 12. 25) ( 12. 26) which ... impedance. Figure 12. 29 Voltage-voltage feedback. • We first calculate the closed-loop gain. Since ( 12. 50) ( 12. 51) ( 12. 52) we have: ( 12. 53) and hence ( 12. 54) an expected r...

... V in ,Q 1 remains off and V out = - I 1 R L = -2 60mV. Since, Eqs. (13.5) and (13.6) can be combined to yield (13.5) (13.6) Beginning with a guess V out = -0 ,2V and after a few iterations, ... Q1 operates as an emitter follower, V out = V in - V BE1 , and Q2 remains off [Fig.13.3(b)] because its base-emitter junction is reverse-biased. By symmetry, if V in is suffic...
