9.4 Charge Transfer Devices

One of the most interesting and broadly useful integrated devices is the charge-​coupled device (CCD). The CCD is part of a broader class of structures known generally as charge transfer devices. These are dynamic devices that move charge along a predetermined path under the control of clock pulses. These devices find applications in signal processing and imaging. In this section we lay the groundwork for understanding these devices, but their present forms and variety of applications must be found in the current literature.

9.4.1 Dynamic Effects in MOS Capacitors

The basis of the CCD is the dynamic storage and withdrawal of charge in a series of MOS capacitors. Thus we must begin by extending the MOS discussion of ...
