Negative Resistance Realisation in Transistor-Resistor-Coupled Device

Abstract

Transistor-resistor-coupled (TRC) device as a composite unit in common-base (CB) and common-collector (CC) configurations offers negative-differential-resistance characteristic. Analytical expressions are obtained for the negative-differential resistance (R_n), peak voltage (V_p), valley voltage (V_v) and peak current (I_p). The theoretical aspects of the expressions are discussed in relation to the experimental observations made on the device in both the configurations.
