Kalkulating Voltage Gain

Thee voltage gain (A is 1; A is 1; FLT: 0 is 3; Xi3; v XX1; FLT: 1 is 3; Xi3;) of a BJT amplifier can be approated using thee small-signal model. It is primarily determinad by the collector resistor (R present 1; FLT: 2 message 3; 3; C present 1; FLT: 3 messad 3; It item impedance of thee transistor.

(R) 1; (A) 3; (A) 3; (A) 3; (A) 1; (B) 1; (B) 3; (B) 3; (B) 1; (B) 1; (B) 1; (B) 1; (B) 3; (B) 3; (B) 3; (B) 3; (B) 3; (B); (B) 1; (B) 4; (B) 3; (B) 3; (B) 1; (B) 1; (B) (B): (B): (C): (C): (R)

where r presentation 1; Xi1; FLT: 0 presenta3; Xi3; Xi1; FLT: 1 presenta3; Xi3; is the input resistance lookeng into the base, calculated as:
