Consider the ECL circuit in Figure P17.11. The input voltages \(A\) and \(B\) are compatible with the output voltages \(v_{O 1}\) and \(v_{O 2}\).

(a) Determine the reference voltage \(V_{R}\).

(b) Determine the logic 0 and logic 1 levels at the outputs \(v_{O 1}\) and \(v_{O 2}\).

(c) Determine the voltage \(V_{E}\) for \(A=B=\operatorname{logic} 0\) and for \(A=B=\operatorname{logic} 1\).

(d) Determine the total power dissipated in the circuit for \(A=B=\operatorname{logic} 0\) and for \(A=B=\operatorname{logic} 1\).
