Jan 17, 2012 · ron = delta vCE/delta iC, at the active region of BJT operation. Simply put: Forward resistance of the Collector to Emmitter PN Junction. Lower the On resistance, lesser is the power disspated by the transistor. Higher the ON resistance, more is the power dissipated by the device.
導通電阻 | 電子小百科 - Electronics Trivia | 羅姆半導體集團
MOSFET的消耗功率是用汲極-源極間導通電阻(R DS (ON))計算。 MOSFET消耗的功率P D 用MOSFET自身具有的導通電阻乘以汲極電流(I D)的平方表示。 此功率將變成熱量散發出去。 MOSFET的導通電阻一般在Ω極以下,與一般的電晶體相比,消耗功率小。 即發熱小,散熱對策簡單。 如左上圖所示,閘極源極間電壓越高,導通電阻越小。 另外,閘極源極間電壓相同的條件下,導通電阻因電流不同而不同。 計算功率損耗時,需要考慮閘極源極間電壓和汲極電流,選 …
cadence中MOS参数的ron和rout的区别 - 知乎 - 知乎专栏
随后,我去百度了一下mos管参数中的ron和 rout ron:大信号情况下的电阻,直流电阻,或者是导通电阻,其值,ron=VDS/IDS,(大写指的是直流,小写是交流,大小写混合是交直流,学电路的时候应该有介绍)
使用比导通电阻的意义,为什么不直接计算电阻。? - 知乎
比导通电阻值(Ron,sp)是评价单极型功率器件性能的重要指标,其物理意义为器件导通电阻乘以芯片有源区(有效导通区域)面积,数值越小表示技术水平越高,即相同导通电阻值产品所需的芯片面积越小。

Chapter 1 Comparison of MOS and Bipolar transistor models
BJT的电流和电压公式. Ice和Vbe呈指数关系. BJT的小信号模型 gm和ro公式. BJT的gm/Ice达到40/V, 远大于MOS. MOS要处于饱和区, 需要Vds>Vgs-Vth. BJT处于饱和区, 只需要Vce>Vce,sat=几倍kT/q=4*26mV, 大约为0.1V. 因此BJT适用于Low Power Supply场景.
