Hello, I need the following book for a huge work in ASIC design. Please, can someone helps me. thanks! Book tittle:"digital Integrated circuit Design" Author: Ken Martin Ed: Oxford University press
any one knows the digital calender circuit with time.please give me
i want to design a digital-analog circuit in 5v/18v cmos technics (design digital parts in 5v,design analog parts in 18v) . I use a structure to realize 5v to 18v.(refe to figure),vin is the structure right (I want to reduce power)? what should I pay attention to in 5v/18v cmos layout? I am a beginner ,Thank you
dear friends.. can any one help me about explaining this circuit..? this is a "digital stethoscope" circuit. the heart beats can be heard in the speaker attached at the end. the heart sound is taken by the microphone. please explain me this circuit operation. Thanks in advance.. the ckt. is as follows
can anyone send me a digital calender circuit

Dear Friends, I am designing 10-bit SAR ADC. The blocks comparator, DAC has been completed. But I am fully unaware of, how to design the digital control circuit. Even I have tried with shift register, ring counter, D-FF , Non overlapping clock and gates. But couldn't succeeded. Even I am getting the problem in understanding the timing function f
help me in speed control of dc motor along with tachometer circuit
I'm trying to figure out how to modify the tachometer circuit in my car to accept the signal from an aftermarket standalone ECU. Unfortunately I DON'T have enough electronics knowledge/background to figure this out first time through on my own :( . Help would be much appreciated. If you want to see my original thread about this on the car forum

Hi, I am looking for resources related to digital AGC circuits to be implemented in FPGA. Can anyone please help me? Thanks. Suma
Can you use microcontroller to generate the output for your clock or do you have to use only digital logic circuit? What I am saying is you can count the frequency of your input clock and generate the output frequency as needed. See image. You will get something like that. Will your clock be synchronized with some other circuit also?
Hi everybody, I builded an old digital tachometer with LED bar ( ) thanks to a few members from this forum (they posted schematic and soure code, ), so maybe someone can help me to rebuild source code to display the time instead of RPM. For exa
In my analog design, I have used digital control circuit. Now I want to simultate them together. I want to synthesize the digital circuit through DC. But how can I get the netlist from digital? Is LDV possible?
The modulator can be either descrete-time (switched-cap) or continuous-time (e.g gm-C) or even both (some stages descrete, some continuous). The decimation filter is a digital circuit, that means FFs and logic.
I want to build a circuit that will pick-up induction from a pulse generated by an engine sparkplug and create a nice digital signal from it.. Any help will be apreciated !

Please upload the schematic files which are missing from The archive only has asm and pcb pdf's there is no schematic. digital tachometer by silicon chip mag. It is what i wanted....
What is the principle of FDT?How to design a fdt(frequecy-digital transform) circuit?
Hi, I've done a digital tachometer using a PIC16F877 and an Hall effect sensor wich "sense" a small magnet attached to the engine shaft but I need to make it more "universal". This tacho. is gonna be used with small gasoline engines wich don't have primary ignition coil signal available. What I'd like to use is to wrap a p
The professor of our faculty has asked us to do digital measurement circuit for the electronic measurement material.. I need your thoughts about what can i do for this project , I don't want to make difficult circuit ,simple is enough but...I haven't yet decide which project should i execute... thanks in advance!!

I'm working on a custom car and I need a switching circuit. I'm more mechanically minded than electical, so I've been unable to work it out myself. I'm hoping someone here would be willing to take a stab at it. Here's what I need: - Constant +12V input. - Two switched +12V outputs, A & B. - One momentary contact pushbutton switch. First pus
When you guys looks a schematic circuits for digital circuits/networks how do u do the circuit analysis for each inputs,outputs,etc for every pin on every IC chip? When i look at a schematic i always thought it was just a topology of trace routing and schematic symbols of electronic parts , thats all it was suppost to (...)

Possible yes, but limited in terms of signal bandwith and dynamic. Assuming you mean an analog signal, the best way is most likely by digital processing. Previously, magnetic tape loops have been used for delays in the seconds range.
You can separate the analog and digital supplies of your circuit by connecting the analog and digital supply pins to separate nodes, and then joining these nodes at the point closest to your power supply. You can join the supplies with the use of inductors, which will block noise traveling between the nodes. This will reduce noise caused by (...)
