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
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
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
why the slope of fequency response of gian in Gray's book is -6dB/octave? i know the slope is -20dB/decade, and i calculate it as follows slope=-20dB/(log8x-log810x) =-18dB/octave what's wrong with my calculation? Thanks!
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. How did
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
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
you will have burden resistor on the CT you use for current sensing, to add slope comp to the signal from this resistor there are myriad ways in the literature to do this. slope comp of current signals is only required for pwm >49%. Regards, Orson.

I am wondering how could I calculate voltages on resistor network ar maybe better resistor mesh. I have thick film resistor with large area. I am wondering what is the voltage distribution on the surface. I have assumed that there are a lot of nodes on surface, and calculated voltages from Kirchoff law. But even use of mat*lab for simple Kirchoff c
Dear all, Xilinx advertizement or datasheet says about the size of FPGA as System Gate. Does anyone know how to come up with the calculation of the system gate? The largest Virtex-II XC2V8000 is about 8 M sytem gates. Does this mean I can implement 8M logic gates? I guess this is definitely not possible. Thanks.
Hi ! Does anyone have Infrared Com. calculation Software or some Optical Link Calculator. ?
The AlCap design tool dimensions the capacitor banks required to implement link-circuit capacitances. When you enter the specific parameters of your application such as voltage, current and ambient temperature, the tool calculates a range of key data including useful life, price index and lists ordering codes for numerous solutions.

calculation of simple arithmatic than usual method. like for example: if u want to multiply 99971 by 99988 without using pen/paper 99971 *99988 -------- 100 - 71=29 100 - 88=12 then 29* 12= 348 ,so put 348 at end then since the numbers are five dig
I'm now doing my project on LNA with embedded active inductor and now I've succecfully design the active L.

How can I determine the dominant pole of an opamp by hand calculation? I am confused with associating each node with a time constant and things like that......where can I find good reference about that? I read Razavi's simply does all the calculation and I don't really get any insight of the circuits......any idea? Thanks a lot. :D

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+

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.

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 (...)
Hi, I've been reading some papers on the common gate LNA recently. I'm confusing by one of the noise issues: most of the papers say that the channel induced gate noise is decoupled and should be neglected, however, the other papers do account for the gate noise in the noise calculation. I'm wondering which one is correct, and why? By the way
