Broadband amplifier circuit using MOS FET

Shown is a broadband amplifier circuit using MOS FET (cutoff frequency 30 MHz). This broadband amplifier is composed of a common gate and common drain field effect transistor amplifier and can be used to amplify high-frequency signals from 1 to 30 MHz.     In this circuit, the input stage VT1 uses a common-gate amplifier, which has wide-band characteristics, and the output stage VT2 uses a common-source output device, which has the characteristics of low output impedance and strong load capacity.
