Step 1: Identify the circuit configuration and make necessary assumptions. The circuit shows a current mirror configuration. Transistor Q_1 is diode-connected (collector shorted to base), acting as a reference current generator. Transistors Q_2 and Q_3 are the output transistors, mirroring the current set by Q_1. All three transistors share a common base voltage and have their emitters grounded. Assumptions: • All transistors (Q_1, Q_2, Q_3) are identical NPN BJTs. • They are operating in the active region. • The base-emitter voltage (V_BE) for silicon BJTs is approximately 0.7 V. • The current gain () for the
