A Differential Sample And Hold Technique That Rejects Offset Voltages, John Adams Davis
A Differential Sample And Hold Technique That Rejects Offset Voltages, John Adams Davis
Retrospective Theses and Dissertations
This research report discussed modern sample and hold theory and techniques and then uses them to develop a new differential sampling concept to solve a real engineering problem, involving the synchronous demodulation of three amplitude modulated direction cosine signals in an unusual noise environment. The problem is discussed in detail and a detailed circuit design solution given. Additionally, the results of a breadboard test of the concept is given that shows the circuit to have a 60dB offset voltage rejection ratio.
