Hello everybody,
I'm trying to calculate dispersion curve for a metamaterial. So, for the beginning and benchmark, I'm considering a very simple problem which is dispersion curve of free space. As everyone knows the dispersion curve for the free space should be a line with the **slope** of 45degree. Thus, I consider a vaccum box (epsilonr=1) with PEC

Hello,
today I saw an book to describe the modeling of power switch for dcdc.
for me there is a question that about the **slope** value **calculation**:
* for the buck, it is obviously that the up **slope** is S1=(Vin-Vout)/L
* while from the book, it is expressed as S1=Vac/L
I am confused about this equation, and does any one can help me to (...)

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

Hi
I need advices on noise **calculation** of ADC.
I'm designing a single-**slope** serial ADC. A two-stage comparator compares Vin with Vramp and drives an NAND-gate. The output of the NAND gate then activates a counter. The counter operates at much higher frequency than the -3dB freq of the compartor.
I want to calculate the thermal noise of t

Hello!
Is this a question?
Is it part of your math homework?
Dora.
dx(t)/dt denotes the **slope** of the signal x(t), obtain an expression for the highest allowable **slope** of the signal in terms of modulation parameters (modulation frequency and step size)
And explain two possible methods to prevent from the **slope** overloading

Hi
Must be a small question.
I wan to know how to impliment Two point calibration and **slope**/Offset **calculation**.
ExampleL
If you have a temperature sensor and you like to calibrate it with two know temperatur levels. There must me some error or difference in the known values and the value given by your sensor.
in software calibration the soft

If its linear, and you have two points, namely, thinner doping and thicker doping values, make a line and find its **slope**. X-axis is the distance. Y-axis is the doping profile.
I am not too sure about my answer, but the reason I think its not a bad method is because the gradient is in cm^-4, which is (cm^-3)/cm. Kinda reverse answering..
If an

Hi,
In the opamp design, first u assume the amount of current to flow at the tail, let say about 100uA. Then to find out the value of λ, take a single PMOS or NMOS. You fix the gate voltage and u sweep the VDS (Drain voltage). Later you plot the curve IDS Vs VDS. So, you can measure the value of ro (output impedance) from the **slope**. Then co

Hi.
There is another way to plot gm of one device, however. But for equal gm (Gm) **calculation** of a specified structure you can measure its **slope** by using .measure statement and DERIV keyword (or something like that) to calculate the derivative (or **slope**) of your parameter 'Id/Vgs'. you can name your measurement in your netlist and write the (...)

Srivats..
...please remember following 2 rules for current mirrors..
1. always use Channel length which is 4-5 * Lmin ...(though this is ideal for DSM i.e < 0.25u)....the best thing wud be for u to characterize the MOS and see for which 'L' Id **slope** is less...use that length
2. Ensure that Vds of mirror X'tors are similar..this takes out (1+
