Hi all,
is this method is valid for calculating n from week to strong inversion?
or is there any alternate
i need to calculate n(**slope** **factor**) to find technology current.
Thanks

When you trace an Id-Vg @ Vd=contant courve of a MOSTand you draw it on a logarithmic vertical scale, you will notice that, for Vg < Vth, the Id current (in the log scale) increases linearly with Vg. The **slope** of this section of the couve is called the WI **slope** or, more exactly, the inverse **slope**.
It tells you how ideal your transistor (...)

Hello All,
I am trying to extract the source-bulk junction capacitance using eldo. The model I have is BSIM3v3 and the confusion is as follows:
There are two capacitances between the source and bulk
1. Intrinsic CSB which is due to the bulk charge.
2. Extrinsic CSB which is due to the junction between the source and bulk
How do I sepa

The key parameter for EKV is 'n', the **slope** **factor**. Our foundry gives us S, the subthreshold **slope**, which can be converted to n by S=ln(10)*n*Ut. The rest of the parameters for calculating Ispec are process parameters which are easily obtained from the model card. Then I size my devices according to weak and strong inversion I-V equations.

simulate ids-vgs curve, plot ids on log scale, measure the change in vgs for current to increase by one decade, this is called subthreshold **slope** S. the relation between S and n is \dfrac{1}{S}=\ln 10 \times n \times U_t. typical value for S is maybe between 80 mV and 90 mV in 130 nm process.

The "n" you are describing is not subthreshold **slope** parameter of EKV model, see pg 194.

The datasheets are specifying a resistance range for a specific illumination, mostly 10 lux. The variation is typically +/- 50%. Furthermore they specify a logarithmitic **slope** **factor** γ, so you are able to calculate the resistance at different luminance levels.

I would suggest that you try to extract the Kp and Kn instead, you will probably also need the **slope** **factor** n. Try to extract Kp,Kn for different values of W/L and see how they vary. Perhaps you could use an average value of the results for the Kp,Kn
I would also be very reserved with the hand calculated results if you intend to use the quadratic

These are ordinary quarter wave transmission lines. They are sometimes made slightly shorter so that the capacitor between the open end and ground can change the resonant frequency. The reactance **slope** is determined by the loaded Q. You control this with the source and load impedance.

Hello,
integration period is actually related to signal frequency, cause i supresses frequencies with a period equal to integration period and it's integer mutiples. It has been often used with 100 ms or 20 respectively 16.7 ms period to suppress mains interferences. Cause it needs a time-to-digital converter with sufficient relative solution, i

and from resonant theory (parallel resoant circuit) Q= **slope**(imag) * fo /(2R).
I am using ADS, I use 2 port simulation to extract alpha and beta..and find Q?? or use one port simualtion to extract Q??

Nominal Resolution of dual-**slope** ADC is usually referring to the resolution of the time measurement of de-integration phase and is simply given by your hardware design. Usable resolution is a matter of various error terms and more difficult to determine. Ponts to consider are
- integration capacitor loss **factor**
- comparator response time
