The following 3-stage amplifier has 2 inputs, V 0.5V and V2 = 2V. Assume the supply voltage for all Op Amps is + 5V-DC. a) Calculate voltage V, at the output of amplifier A b) Calculate currents i, into the 10 2 load R, and i, at the output of amplifier A c) What type of amplifier is Stage-2, and what is the voltage V, at its output? d) What type of amplifier is Stage-3? How large can V2 be before amplifier C saturates? (Assume that Vi2 is a positive voltage source) Example 1: Stage 1 Stage 2 Stage 3 500 ww 100 Q 25 Q 100 N B ww 100 0 50 0 10 0 50 0 0.5V Vi2 The following 3-stage amplifier has 2 inputs, V 0.5V and V2 = 2V.
