Question

1. (20 points) A BJT class A voltage-follower output stage powered by a +15V de

voltage source drives an 892 load with a 4V peak sinusoid at 1 kHz with 6V dc

bias value. Ignore the effect of turn-on voltage for the amplifier.

a) Find the power delivered to the load.

b) Estimate the power dissipated in the transistor.

c) Find the efficiency of this amplifier.
