Dot parameters LTspice - Transconductance of MOSFET
Below is a very simple circuit to extract the transconductance value of the MOSFET.
As it is known, transconductance is known as Delta (Id) / Delta (Vgate).
For the gate voltage, I defined it as .step ...

Short Circuit Transconductance Cadence
Hello, I am curious about hand calculation about overall Gm by using short circuit transconductance.
I got M2 of gm is 1.176mA/V, M2 of gmb is 0.2078mA/V. It should be around 1.14mA/V by using short ...

MOS transconductance plot using LTspice
I am trying to plot the transconductance of a MOS using LTspice in DC sweep. However, I heard that there is no dy/dx function in LTspice. Therefore, I came up with another way.
Keep the drain voltage ...

What would happen to the drain current of a D-MOSFET at cutoff voltage when we are going to plot the tranconductance curve?
Here,
$$I_{DSS} = 8 \,\textrm{mA}$$
$$V_P = -6 \,\textrm{V} $$
Equation for the drain current,
$$ I_D = I_{DSS} \left(1 - \frac{V_{GS}}{V_P}\right)^2 $$
So, the cut-off voltage is where the Drain ...
