(8 marks) Consider the circuit below with \( \mathrm{V}_{\mathrm{CC}}=15 \mathrm{~V}, R_{\mathrm{L}}=15 \Omega \) : a) Find the largest value of quiescent current \( \left(I_{0}\right) \) possible if the quiescent power in each BJT must be kept to less than \( 30 \mathrm{~mW} \). b) What is the small signal voltage gain when \( V_{0}=0 \mathrm{~V} \) ? c) As \( v_{0} \) swings between \( +10 \mathrm{~V} \) and \( -10 \mathrm{~V} \), find the smallest value of emitter current of the NPN. At what output voltage does it occur?
