In terms of material selection, the application of high-k materials significantly improves the gate's electrostatic control capability over the channel.
As the final "purification gate" in the power supply chain, voltage regulators and LDOs, with their simple structure, fast response, and extremely low output ripple, have become key components for ensuring the stable operation of precision circuits.
Due to its unique structure and operating principle, the field-effect transistor (FET) exhibits extremely high input impedance in electronic circuits, far exceeding the several thousand ohms of a bipolar transistor.
Among these, the triode is one of the most basic and crucial components. Because it can control a large current with a tiny signal, it is figuratively called a "magic switch" in the electronic world.
Against this backdrop, voltage regulator & LDO, as core devices for ensuring power supply quality, have become the "power guardians" protecting sensitive electronic devices with their precise voltage regulation capabilities.
The transconductance parameter of a field-effect transistor plays a decisive role in amplifier design. It not only directly drives voltage gain but also influences frequency response, linearity, and system stability. A high transconductance transistor mea
