基本概念

1，Where did Digital Logic come from?

Boolean Algebra George Boole true，false；and ,or,not
Switching Theory

Claude

Shannon,

 utilizing the properties of electrical switches to compute logic functions
The Transistor Bell Laboratories. the ability to be used as a switch and allowed the creation of much smaller, faster, more reliable, power efficient circuits as there are no moving parts.

2，在晶体管开关的栅极端施加控制电压，晶体管开关就可以打开或关闭。 它控制着漏极和源极之间的电流流动。 有两种主要类型的晶体管，称为n型和p型。 image1 对于n型晶体管，当没有电压(GND)加到栅极时，晶体管充当开路开关，断开漏极和源电路。 当一个电压(比方说3V)加到门极时，晶体管充当一个连接漏极和源极的闭合开关。 p型器件的工作原理与施加在其栅极上的电压相反(互补)。

Summery

  • Electrical switches can be used to create circuits for computing functions.

  • A semiconductor transistor can act as a miniature switch.

  • Transistor switches can be grouped and arranged to make simple boolean logic operators.

  • Boolean operators can be combined to create more complex circuit functionality.

  • Complex circuit functionality can be designed, manipulated and simplified using Boolean Algebra.

  • Note: Intel’s newer 8-Core i7 Processor uses approximately 2.6 billion transistors and newer server processors like the 22-core Xeon Broadwell uses over 7 billion
