WebSep 8, 2024 · To clarify the phenomenon, let us recall the formula of the common base current gain cutoff frequency \$f_\alpha\$ deduced by using the Giacoletto (Hybrid-Pi) model of the BJT : $$ f_\alpha = (\beta_o + 1)f_\beta\simeq \beta_o f_\beta=f_T.\label {1}\tag {1} $$ where \$\beta_o\$ is the ordinary low frequency common emitter current gain, … WebA common base amplifier is one of three basic single-stage bipolar junction transistor (BJT) amplifier configuration, typically used as a current buffer or voltage amplifier. In this configuration, the emitter terminal of the transistor serves as the input, the collector the output, and the base is common and connected to ground (through C b).
