The Design of DC Servos
DC Offset Control by Servo-loop
Noise, Component Values, and the Roll-off
In the section of this book dealing with input stages I have gone to some lengths to demonstrate that a plain unassisted amplifier — if designed with care — can provide DC offset voltages at the output which are low enough for most practical purposes, without needing either an offset-nulling preset or a DC servo system. For example, the Trimodal amplifier ...
