Differential Input Resistance in BJT Differential Amplifiers Formulas

Differential Input Resistance is defined as a single-ended "resistor" (connected between the input and ground) in the case of differential mode. And is denoted by R_id. Differential Input Resistance is usually measured using the Kilohm for Electric Resistance. Note that the value of Differential Input Resistance is always negative.
