Question at position 1  Consider the following circuit where Ra=1k, Rb=5k, RL=32. Assume that the Op-Amp is ideal and for the BJT β=100 and VBE=0.7V Find: a) The output voltage and the collector current of the BJT assuming Vin=-0.5V Vout = Question Blank 1 of 3[input] V Ic = Question Blank 2 of 3[input] mA Hint: Notice that the current on Rb and RL must come from the emitter of the BJT. b) The maximum values that |Vin| can have while keeping the Op Amp out of saturation. Notice that Vout can not be negative as current can't flow into the emitter of the transistor. |Vin,max | = Question Blank 3 of 3[input] V
