Some Models and Implementations of Digital Logic Functions Using Junction Charge-Coupled Devices

摘要

The thesis describes some models and implementations of digital logic functions using junction charge-coupled devices (JCCDs). It aims to furnish the reader with a working knowledge of the physical principles of JCCDs as used in logic applications, and to provide him with tools for the concise and precise description of the basic structures and synthesis of JCCL. The core topic of the first part is the analytical solution of a simplified JCCD. In JCCD literature, there are several equations expressing the amount of charge that can be stored in a junction charge-coupled device. Using the simple model, a correct expression is derived. Also, a new concept of the charge transport in the junction charge-coupled device is introduced, which is not based on the charge handling capacity (= the maximum amount of charge that can be contained) of the potential well from which charge is leaving, but which is based on the equality of the electrical potential in the driving and receiving well.
