13.17 Determine the loop gain of the feedback loop in Fig. 13.23. Break the loop at the input of the Q5−Q6 mirror. Since the input resistance of the mirror is low, ground the connection of the collectors of Q1 and Q2. Apply an input test current it to the current mirror and find the feedback current that appears in the combined connection of the collectors of Q1 and Q2. Assume IREF remains constant. Loop gain
