What is the Difference between MOM, MIM and MOS Capacitors?17 April 2025
This article mainly introduces the structure, principle, advantages and disadvantages of MOM, MIM and MOS capacitors and the difference between them.
What is a variable capacitor?16 April 2025
A variable capacitor is a capacitor whose capacitance can be adjusted within a certain range. When the relative effective area between the pole metal plate or the distance between the plates is changed, its capacitance changes accordingly. It is usually used as a tuning capacitor in a radio receiving circuit. Its two major types are Air dielectric variable capacitor and Solid dielectric variable capacitor. It is widely used in tuning and amplification, frequency selective oscillation, and other circuits.
How many Transistors in a CPU?15 April 2025
Transistors are the basic building blocks that regulate the operation of computers, mobile phones, and all other modern electronic circuits and is the basic unit of the CPU. Transistors can be packaged independently or in a small area. Integrated circuits can accommodate 100 million or more transistors.
