Web• The input impedance of emitter follower is exactly the same as that of CE stage with emitter degeneration. This is not surprisingbecause theinputimpedance of CEwith … WebJun 16, 2005 · Re: emitter resistance I cannot deduce the formula, but: k=Boltzmann's constant; k=1.380658E-23 [J/K] T=absolute temperature T=273.15+t [°C] [K] q=electron's charge q=1.6E-19 [C] So at room temp (300K), this quantity kT/q (thermal voltage) works out to about 25.89mV. So if the temperature is less than 300K (27°C), it will be closer to 25mV.
