 Single-ended Ground Centered Analog

Architecture

The advantages of this architecture include ideal differ-

ential linearity, no distortion mechanisms due to resistor

matching errors, no linearity drift over time and temper-

ature, high tolerance to clock jitter, and a minimal set of

external components.
