Hi: How to design a one-transistor Super-Regenerative Receiver? Or where I can find information about this Topics? Great Thnaks hslin000
The basis of good design is good tools and good parameters. We have some wafers with the PCM (process control module) between the dice. I want to extract parameters from those, for checks. What is the best way to generate simple but efficient models ? What is the good software ? UtMos? What are the good measurements ? with what kind of tools ?
Hi I need some tutorials or IEEE Papers on UWB LNA using pHEMT transistor. Thanks Kella
oasis4355, kevpat is right. They are not the same (not even close). The unijunction transistor is a switching device. Its primary parameter is the "intrinsic standoff ratio" (eta). The device has two bases and an emitter. When the emitter voltage exceeds a value equal to the inter-base voltage times eta, the devices switches and the inter-bas
I can see some of your transistors, but you need first to place them then use SHIFT+F. Sometimes Layout XL looks like lagging in such issues. Try shut down icfb and restart. Tell me the results. D.
can you provide tutorials for sizing transistor so that we achieve maximum gain in a comlicated large circuit
Hi members, I need materials/tutorials on CMOS transistor W/L sizing. In fact I need to understand the 1/K rule used in the inverter based Oscilators. Any help will be appreciated. I'll donade 20 Points as a reword for real helps. Best Regards, Master_PicEngineer.
Hi Everyone, I wanna some tutorials regarding transistor .Can anyone give me a Good tutorial or a good link so that i can easily understand it.Basically i m not confident how to calculate base current,collector current,how much collector give us max current etc.
Hi all, I need progressive tutorials (if possible exercices and solutions) on the gm/Id methodology for circuit's transistor sizing. I know the principle but I can't apply it when dealing with differenctial circuit like differential delay cells. Any help will be welcommed. Thanks in advance. Cheers, Advares.
hi all Please...does anyone has ebooks on fundamentals of RF technology??? hi you can see this ebook for RF and microwave and i advice you for RFID to handlbook i hope you find what you need
Hello Is there any tool which can draw my transistor level layout, by a verilog netlist? I have used tools like Microwind but this tool isn't complete and there is no way to limit size of layout and it isn't very clever in drawing automatic layout so it will providing a big layout which is not acceptable in area size!!
Hello all, Anybody is using Cadence UltraSim? I have been used Spectre and Hspice, but I don't have any experience with Ultrasim. I think this sound stupid, but I'm wondering Ultrasim can take the Spectre transistor models? I will also appreciate your help, if you can point me out some tutorials regarding usage of UltraSim. Thank you,
How do you know which hFE value to use from a transistor data sheet in biasing a bipolar npn transistor in common emitter to get desired IC current when Ib current = IC/hFE is applied ? Take a bc548 npn transistor for example how would you calculate the biasing current required on the base to get a desired current on the IC that = (...)
I keep reading MOSFET tutorials that describe the MOSFET as a voltage controlled device that has extremely high input resistance (OK so far) but then state "NO current flows into the gate" (for example The MOSFET or Metal Oxide Semiconductor FET Tutorial ). Why do
Cadence's Conformal-GXL (or Conformal-Custom) can take read transistor spice level netlist and convert that to a verilog structure. The verilog structure can in turn be verified against RTL. You will however, need the Conformal-LEC-Custom license if you want to run the RTL to transistor level checks. Golden: RTL Revised: spice -> Verilog Conform
Small variations in the base current will have big variation in the collector current. Check transistor explanation in the following link tutorials, Electronics made EASY, Williamson Labs Alex
i want to start to desing amplifer on stage with transistor to multi stage could you interduce me with good article or books that explain it very well? i want a book ,text or .... that explain how can design a ampilfer with transistor with eqution and use transistor data sheet.... Thanks a lot
Hello, I am looking into voltage regulators, but so far am having difficulty finding good references to learn about them. Are there some references, such as papers, textbooks, tutorials, etc, that discuss voltage regulators and transistor level designs? Thanks.
In this pdf for the 2N3904 What part of this data sheet should I be looking at to figure out what my bias should be? I want to experiment with my signal generator, so I can see the transistor in action. Every other time I have tried this I get annoying peaks(clipping) that do not reflect
It's a typo error there, a vice versa situation… :grin: 1. The BJT is a current-controlled device since its output is determined on the input current, while FET is considered as a voltage-controlled device, because it depends on the field effect of the applied voltage. 2. The BJT (Bipolar Junction transistor) uses both the minority and maj
hi can anyone tell me what is q factor in transistor and how i can use it practically? thanks
I cannot understand why the current at a particular emitter-base voltage decreases as we increase emitter-collector observe, at a particular Vbe, the Ib is decreasing as we increase the Vce. What is the mechanism that is causing this to
Take a look at these to learn about transistors tutorials, Electronics made EASY, Williamson Labs transistor Circuits Alex
Here is an explanation of biasing: Some more links can be found in
Hi edaboard... I am having a confusion on a transistor K3567 about the voltage flow.... Pin 1 is GATE which makes the circuit on & off.... But I want to know whether the voltage flows from 'SOURCE to DRAIN' or 'DRAIN to SOURCE'???? Please simplify it.....
hello everyone i have some question 1- what do u mean by biasing in transistor?? 2-list the different types of biasing? 3- what is the operating point or Q point of transistor? 4-why it necessary to have a CAPACITOR between the input and the base of the transistor? thanx
hi, newbie here. we are given a project using transistor as a switch. can you please give me an example or any reference how to use sound as input and light as an output. i don't have any idea how to start to make plan for it. please.
Hi packet, such an oscillator could be built in different ways. An easy possibility is a colpitts LC-oscillator. Look at this page ( ), there are some explanations about. You can also build a VCO with this osci-type. The choice a transistor depends on your needed outputpow
As i described in a previous post now when placing pins, for example the invertor, I placed an IN, OUT vdd! and a gnd! I DRC and extract the design OK. Viewing the extracted layout the nmos transistor is the wrong was round. Now when when it comes to simulate I have to specify the IN the vdd! and gnd! however they are not under global nets but un
Minicircuits and others make IC amplifiers that will do this. If all you want is the amplifier and not the knowledge of how to design one from a transistor, this is the best and cheapest source. They sell the ICs and also packaged versions in metal boxes with coax connectors. is where to start. Sele

The best "tutorials" are in books for electronics. Sendra/Smith Microelectronic Circuits have a simple yet very good presentation for semiconductors. If you want something more advanced, with more explained mathematical psice models I suggest Lacker/Sansen " Design of Analog Integrated Circuits and Systems". Also very good and with layout examp
wolfheart_2001 the thing is that when you design a discrete transistor amplifier you have to ensure that your output is not beta dependent. the reason is as you have found out that different transistors of the same part number have different values of beta and infact transistors on the same silicon will have different values of beta. and (...)
It is basically a device, like a bipolar transistor, set up to oscillate. But there is a RC bias circuit (with an audio frequency time constant) that quenches the oscillations just at the point that it is ready to take off. Since an oscillator has "ionfinite gain", this almost oscillator has almost infinite gain. Not a bad trick for one device.
for bootloader see this nice site.... . Regarding need LD293 control direction and speed of the motor. If you want to control..the speed only, a transistor or mosfet will do that. Hope this helps
pcb board -> silicon wafer resistor -> poly silicon capacitor -> metal transistor -> silicon semiconductor that is ok!
you can using chopper cctinclude transistor and coil and capacitor to change the avarge
One point that people miss while following those tutorials is that port instance at ouptput and input. They should be given a proper source resistnace, according to your circuit. Dont follow blindly the same procedure if you are designing with CMOS as the given examples are with Bipolar transistor. Calculate appropriately your input and output
