Voltage Regulation
10.1 Introduction
In Chapter 3, Table 3.1 introduced a comprehensive listing of cases. In between the cases for inverting and non-inverting gain was a line on the table when op amp gain m=0 and offset b is positive, negative, or zero. These fall into the category of voltage regulators, and have their own set of interesting challenges.
I have included some design utilities on the companion website, which are discussed at the end of this chapter.

10.2.1 Virtual Ground: b=0
Let’s start with the simplest case, b=0. This is the ground reference point of a circuit, and requires no active circuitry. However, active virtual grounds are sold, and find a niche market in line driving applications. Rather ...
