I recently made a signal generator, in which the op amp needs to be powered by positive and negative 12V. The total current of -12V should be 200mA, and it is best to have a maximum current output of ...
Capacitors are the most common and commonly used devices in circuit design. They are one of the passive components. Active devices are simply devices that require energy (electricity) power, and devic...

My colleague and I spent the day chatting in the hotel bar. We had met with several customers. We were both wondering how come these engineers we were meeting knew almost nothing about analog techn...[Details]
The data collector of the automatic weather station is generally designed based on a single-chip microcomputer or a PC/104 bus controller. It has the characteristics of good compatibility with PC, low...[Details]
1. What is temperature?
Heat is a type of molecular motion. The hotter an object is, the faster its molecules move. Absolute zero is defined as the temperature at which all molecular motion ...[Details]
