Before going to the depth of this article, there are a few basics that you should know. Especially, about the exact working of electricity. Electricity mainly depends on three parameters. They are voltage, current and resistance. These three parameters are related to each other and a proportional change occurs to these parameters, when a change is subjected to either one of them. Voltage is the parameter that makes the electric charge move. Current is defined as the rate of...

  Resistors Resistors are considered to be the most used and the most important component of all the electronic circuits. Take a look at the working, types and also use of resistors in the field of electronics. We know that the basic idea of any electronic circuit is the flow of electricity. This also is further categorized into two – conductors and insulators. Conductors allow the flow of electrons, while insulators do not. But the amount of electricity that...

Charge Coupled Devices (CCD)

john January 3, 2011 5 Comments
Charge Coupled Device (CCD) – Definition CCD was developed in the year 1969 by Willard Boyle and George E. Smith at AT & T Bell Labs. It is a shift register device which can be used for the movement of electrical charge within the device. This movement can be from one area of the device to another and the digital value of the moved charge can be easily found out. When the signals are moved, one at a time...
