Abstract

Expressions are derived for input resistance, output resistance and ratio of input to output voltage and current at low frequencies for transmission in both the base-to-emitter and the emitter-to-base directions. These expressions are extended to the carrier frequency range (up to approximately twice the alpha-cutoff frequency) by considering the effect of the variation of alpha with frequency, of collector capacitance and of load capacitance. Experimental evidence is presented which verifies the equations obtained.
