SECTION 3: THEORY OF OPERATION
3.1 OPERATION PRINCIPLES OF THE CCD
A CCD (Charge Coupled De vice) consists of MOS
(Metal Oxide-Silicon) capacitors arranged in a regular
array. It performs three functions connected with handling electrical charges:
Photoelectric conversion (photo sensor)
Incandescent light generates electrical charges on the
MOS capacitors, with the quantity of charge being proportional to the brightness.
Accumulation of electrical charges
When voltage is applied to the electrodes of the CCD,
an electrical potential well is f ormed in the silicon la y er .
The electrical charge is accumulated in this well.
Transmission of electrical charge
When high voltage is applied to the electrodes, a
deeper well is f ormed. When lo w v oltage is applied, a
shallower well is f ormed. In the CCD, this property is
used to transmit electrical charge . When a high v oltage is applied to the electrodes, a deep electric potential well is f ormed and electrical charge flows in from
the neighboring wells. When this is repeated o v er and
over among the regularly arranged electrodes, the
electrical charge is transf erred from one MOS capacitor to another . This is the principle of CCD electrical
charge transmission.
