and high quality Features: Designed to control the output loop current by regulating the electric field effect of the input loop. The control input terminal of the MOSFET requires a very low input voltage, resulting in high input resistance. Utilizes majority carriers for conduction, providing better temperature stability. The field effect transistor offers strong radiation resistance. Absence of shot noise caused by electron diffusion during random motion ensures low noise performance.
