delta Id/delta Vi = Gm Gm=tranconductance=1.5 milli Siemens Id=Gm*Vi |

Thanks to Shalini. I just wanted to see the formula used. |

Thanks shalini to remember Gm=1/R=1/Resistance=Transconductance |

Thanks to shalini. |

Gm=Iout/Vin |

dI/dV = gm(transconductance). >dI = gm*dv. >dI = 1.5m*2;. >dI = 3mA. |

Id = 2 sqrt(gm*Vgs). gm = 1.5x10^-3. Vgs = 2. So Id = 3mA. |

What is the input delta, what is the drain current delta? |

Shadan said: (Nov 24, 2017) | |

Transconductance(gm)= Del( ID) /Del( VGS) and also Transconductance is reciprocal of resistance so we no that Resistance =V/I. so transcondustance=I/V. Then you will found 3mA. |
