Consider the telescopic op amp designed in Example 9.5 and repeated in Fig. 9.43 with bias current mirrors. Suppose
suffers from a 1% current mismatch with respect to
, producing
mA rather than 3 mA. Assuming perfect matching for other transistors, explain what happens in the circuit.
Example 9.5
For the circuit of Fig. 9.9, explain in which region each transistor operates as
varies from below
to above
.
