跨导 Transconductance

(重定向自Mutual conductance)

跨导英语:Transconductance)是电子组件的一项属性。电导(G)是电阻(R)的倒数;而跨导则指输出端电流的变化值与输入端电压值之间的比值。通常用 gm 表示。

对于直流电,跨导可以定义为:

g_m = {\Delta I_\mathrm{out} \over \Delta V_\mathrm{in}}

对于交流电小信号模型,跨导的定义相对更为简单:

g_m = {i_\mathrm{out} \over v_\mathrm{in}}

Model transconductance device

Transconductance (for transfer conductance), also infrequently called mutual conductance, is the electrical characteristic relating the current through the output of a device to the voltage across the input of a device. Conductance is the reciprocal of resistance.
