You’d use a FET if you needed a high-impedance audio preamp or a low-noise RF ... transistor circuit configurations have equivalents with a FET; common-emitter becomes common-source, common-base ...

[Paulo] just tipped us about an Excel based high frequency transistor amplifier ... of the characteristics of two class A common emitter/collector amplifiers for specified loads.

Abstract— Today’s on-chip Analog/Mixed-Signal and RF (A/RF) systems have reached a limit of size and complexity where transistor ... amplifier. The fully differential architecture of the analogue ...
