Gummel plot
In electronics, the Gummel plot is the combined plot of the base and collector electric currents, I c {\displaystyle I_{\text{c}}} and I b {\displaystyle I_{\text{b}}} , of a bipolar transistor vs. the base–emitter voltage, V be {\displaystyle V_{\text{be}}} , on a semi-logarithmic scale.
