Consider the circuit in Figure P17.7.

(a) Determine \(R_{1}\) such that \(I_{\mathrm{REF}}=0.20 \mathrm{~mA}\).

(b) Determine the values of \(R_{5}\) and \(R_{6}\) such that the maximum currents in \(Q_{5}\) and \(Q_{6}\) are \(0.12 \mathrm{~mA}\).

(c) Consider \(A=B=0\). What is \(I_{Q}\) ? Using the results of part (a), find \(R_{C 1}\) so that \(v_{O 1}=-0.7 \mathrm{~V}\).

(d) Consider \(A=B=-0.7 \mathrm{~V}\). What is \(I_{Q}\) ? Using the results of part (a), find \(R_{C 1}\) so that \(v_{O 2}=-0.7 \mathrm{~V}\).
