Large‐Signal and Small‐Signal Analysis on BJTs DC Equations for BJTs: (Reminder) + ¼ L + Ì k ALet’s perform a small-signal analysis to determine an approximate relationship between i c and v BE. Note that the value of v BE BE be ()tV vt= + is always very close to the D.C. voltage for all time t (since v be ()t is very small). We therefore will use this D.C. voltage as the evaluation point (i.e., bias point) for our small-signal analysis.The key to implementing small signal analysis is to first select a DC bias value and analyze the behavior of the circuit. The goal is to determine the transresistance (the inverse of the transconductance) for your nonlinear circuit elements at this particular DC bias. Once you know the transconductance for each nonlinear element, you can ...
