Describe the differences between NPN and PNP BJTs. Define the transistor parameters alpha and beta, and determine them from device curves and/or circuit currents. Draw and explain the various regions of a BJT collector curve, along with Early voltage. Describe and utilize the Ebers-Moll BJT model. Describe the concept of the DC load line. Solve and design basic switching and driver circuits utilizing BJTs.
