*8.16 The circuit shown in Fig. P8.16 is known as a current conveyor. Q1 Q3 Q4 VEE Q2 Y Q5 X Z Figure P8.16 (a) Assuming that Y is connected to a voltage V, a current I is forced into X, and terminal Z is connected to a voltage that keeps Q5 in the active region, show that a current equal to I flows through terminal Y, that a voltage equal to V appears at terminal X, and that a current equal to I flows through terminal Z. Assume β to be large; corresponding transistors are matched, and all transistors are operating in the active region. (b) With Y connected to ground, show that a virtual ground appears at X. Now, if X is connected to a +5-V supply through a 10-k resistor, what current flows through Z?
