ABSTRACT:
A high frequency amplifying device comprises a field effect transistor-bipolar transistor darlington pair. Such a device combines the main desirable features of both field effect transistors and bipolar transistors, therefore, having a high input impedance that is typical of FETs and a high transconductance (or high current gain) which is typical of bipolar transistors.
