H4P1: Zener Regulator
A non-ideal voltage source can be modeled by a series combination of an ideal DC voltage source, a resistance, and a small-signal voltage source. The small-signal source is included to represent the noise inherent in the source. This model is illustrated in the figure below:

In practice, connecting the non-ideal voltage source to a load may result in undesirable effects due to the noise voltage vo appearing across the load.

This problem studies such effects and how a Zener diode may be used to ameliorate the problem.

Assume that VI=13.0V, RIN=1kΩ, and vi=20.0m
