hi... i want do pwm program with 8051.. program is finrly working.. but m using sl100 darlington pair to drive the motor,but the transisters are buring out after few minutes,even i checked the current ratung, its more than sufficient... plz help me out... very soon plz..... Test your circuit with a smaller resis
Hello, I built a push-pull amp with transisters that have a Ic Max rating of 3A. They are operating at 1.1ARMS or less. They get pretty hot, but I was wondering if I should spend the money on heatsinks or just drill some holes in the top of the enclosure. They are the TIP31 and TIP42 that you get at radio shack. George Actually it would b
Normally the input differencial transisters should be biased at half VCC. All the transisters should work in saturation region.
you can make solar cells with spoiled power transisters
is possible to get some igbts or power transisters Added after 2 minutes: high power white led is not readly available , is it will be able to get as sample
I have to make a project of 4x7 segment display in which I have to display reading of an up down counter, I am sipmply using 7 ports of atmel for rows through transisters and 4 ports for colomns(common of displays) through transistors, I dont know how to scan it using timer Intrup mode so that all the display scanned and show the reading. now I wan
I have been looking for freewares to draw documentations, but never found it. And a software to draw timing diagram, responses, analog waveforms, wtc?
in an opamp design, some of the transisters' widths are big that (in the range from 60u to 200u in tsmc0.35 process) i set fingers for all of them in cadence, and i expect parasitic will be reduced such that unity gain frequency will be improved, but the simulation yields the same result, could anyone share some experience?
Yes exactly what i want to do there. Can you help me with this? I know i need some transisters (but not sure what type) and need resisters to step down from 5v to 3.5v
great answers to my first question dude but sori for 2nd question i am unable to understand ur concept but i am trying make my own concept plz check it out it is right or wrong my concept are very low i am pursuing ece i have read ae in kollege but it is totally based on cramming i want to make my concepts strong in electronics back to the questi
From my understanding transistors can be used for amplifying and switches. What i am interested in is the switching (either on or off). I have a switch at the moment (sorry for my explanation my terminology is a bit off) From parallel port cable comes out to a transistor. middle leg is connected to cable coming out. Negative side goes back
am not able to increase the gain of the pre-amplifier stage beyond 2V/V. is this gain sufficient for the design. gain is low because the load for M1 and M2 transisters are in trode region(according to the design). how can I design the dynamic latch.
If I build a 20-bit adder with transisters in analog library (because I don't have digital library), is it much different from the adder building with digital standard cell? And what should I pay attention to build it? When it is finished, how can I simulate to make sure it works right? How to add input signals for a 20-bit adder?The software I use
If I build a 20-bit adder with transisters in analog library (because I don't have digital library), is it much different from the adder building with digital standard cell? And what should I pay attention to build it? When it is finished, how can I simulate it easily? The software I used is Cadance. Thanks!
caringin, if you read the third line of Davood Amerion's last post, you will see the answer (you have some voltage drop across the output transisters when you draw current = 600 mA). jonathan
i want to design a protect circuit for 3.8V Li-battery using only ordianry analog device like transisters and resistance to limit it's voltage above 3 V, who can lend me a help, many thanks. hmm, look around after protection circurit on maxim, linjear technology etc. is not simple to built itself depend of protecti
Hi How can I design such a latch, that it's input is logic high and low ( dvdd dgnd),and clock. And it's output is two voltage level.for example when input is high and clock is high the output is 1.8v, when input is low and clock is high the output is 0.6v.(vdd is 3.3v). how can I realized it using minum transisters, and is there any article
