In fact there is no "CMOS transistor" - there are NMOS and PMOS. As a rule "RF guys" appear to prefer the zero-VT device for gm and IDsat, relative to capacitances. You can find canned NMOSFETs for lower frequency applications. Anything over maybe 1GHz probably wants integrated transistors. Kind of wasteful for a 1-transistor LNA (study p
Can anyone help to download the NYUSIM :The Open Source 5G and 6G channel Model Simulator software I try to complete the form to download a .zip copy of NYUSIM v2.01 for Windows many times,but it?s not work. Thank you for help! the link:
Hello! I'm intensively looking for a specific device. As you know, there are devices called FM transmitters for use in old cars, in which there are still old radios without a USB interface. Such a device in a sense "impersonates" a radio channel, giving itself music on a given frequency, which can then be played on our old-fashioned radio. So
Thank you so much, it is somehow time-consuming because in my project that I have used multi-channel structure is so complex to do this procedure.
Hi, How to connect differential probe bnc pin and ground pin to oscilloscope. I know how to connect differentil probe bnc to oscilloscope channel but how to connect ground pin of differential probe to oscilloscope?
If you had the supplies handy, an analog switch IC would probably be your better bet. Your network values are high, analog switches can be had below 10 ohms per channel. Far lower standby current than what you've got now.
Qdepl is how much charge to negate the doping at the surface. That is a pretty straightforward thing. Qinv is the additional charge to then invert the same region, but how much? That's "squishier" and yet the more interesting, as it goes right to channel conduction strength. Because it's whatever you want it to be, good luck getting a simple answ
Hi, I am considering AD9257 ADC for my application. The ADC chip is octal which means 8 ADC on chip. The resolution is 14 bits and sampling rate is 65 MSPS. Each channel has serial LVDS output. There is a statement on the first page of the datasheet which reads. "Ease of Use. A data clock output (DCO) is provided that operates at frequenci
If, and that is a big if, I am understanding you correctly: You require three clamp type probes, a single differential high voltage probe, and a 4 channel scope. Connect the high voltage probe to channel 1 and set the trigger to that channel. Clamp the current probes to each phase and feed them to channels 2,3 and 4. (...)
MOS (p type) 1) General Question: Why thin charge sheet on the metal side ? Is it because positive bias on metal side will attract the electrons leaving immobile positive ions at the metal -oxide interface ? If yes then why not we get this thin charge sheet at surface of the metal where we have the positive bias ? 2) Figure a) and b) are the cas
You'll ask for the channel noise spectrum and AC signal characteristic to decide about an optimal detection algorithm.
some time ago i needed a portable power supply that could lit led arrays so i can test various tv sets brought to my repair shop,so i decided to built one.this little device works perfect for 2-3 years now and all the repairs im making is done with the help of it. here is the schematic and various photos and below a video presentation on my youtu
hi! i have 10 DC OK galvanic isolated signals and need to AND them into one signal. if i connect outputs of 10 optocoupler in series and than detect by comparator when all of it is on, is it good shem?
Hi Guys VLSIFaB is the most trending chennel in VLSI now, dont forget to review it.
Dear friends, In the early steps of designign the op-amp is to select the appropreiate value of overdrive voltage (Vov = Vgs-vth) to meet different criteria (ICMR, OCMR, ...etc) in the Jakob book procedure he use for long channel transsitor the rule of Vov = 5% VDD. in Holberg and Gregorian book the authors stated that if (Vgs -Vth) < 100 mv
Hi, For a low-IF receiver, how do we deal with the in-band image problem? take this figure for example, say that it's a low-IF receiver with f_IF = 1 MHz. Thus the image for one channel could be another channel, which can't be filtered by your band-selection BPF. Then how do we solve the image problem? 155735 Do we
You didn't split your bus out correctly. Look at this-"creating a Multichannel design":
Hi, I want to measure phase voltage of bldc motor which is having delta connected system. Since there is no ground terminal in delta. I am confused to measure the phase voltage of motor with oscilloscope. Can anyone tell me how to connect the channel probes to measure phase voltage of delta connected motor?
Dear friends, In the Jakob book he discussed about selecting the suitable value of the overdrive voltage of the transistors in the operational amplifier. for long channel he is using Vov = 250 mV (VDD= 5V). My question how the overdrive voltage affect the speed of the operational amplifier ? consider please for example GBW = gm1,2/CL. in th
Equations only tell you, what their author told them. Equations are always (or at best) simplifications of reality. When most people talk about "shorter gate" being "faster" they often talk at "high level" comparing a (say) 90nm transistor to a 250nm transistor. The channel gm is higher, true. But "speed" has other elements such as the drawn d
