Description

The  NJU7664  is a  voltage converter for GaAs FET,  which  contains CR oscillation circuit and dual operational amplifiers.

The voltage converter of NJU7664 is a circuit operated by the charge pumping  system, and it generates the negative  voltage from the positive  power supply. Furthermore the charge pumping capacitor is  incorporated.

Both of two operational amplifiers of NJU7664 with the gain resistance which is  set up at  -OdB output  the negative  voltage by the inverted input  voltage.

The  NJU7664 realizes to  operate the GaAs  FET requiring the  negative gate biassing.
