Signal Chain Designer: FET Current Noise in Amplifiers

0001-01-01

MOSFET and JFET amplifiers have extremely low current noise at low frequencies, but it increases at higher frequencies. Many applications have enough capacitance at the input that the extra noise at high frequencies doesn't matter, , but in some applications, it can. This video shows how ADI is now characterizing this effect and how we model it in Signal Chain Designer.
