hi, I'm an asic design engineer and never got involved in analog. Currently I'm embedding a microcontroller into my chip. This chip should have analog parts (specifically an A/D converter). I was wondering how to implement this structure with analog libraries and how to proceed the design flow which was started with VHDL? I mean, how should I integ
Hello! Need a high speed (and 2.0 compiliant) USB host chip for embedded aplications. High speed is 480 Mbit/s. There are many chips in market can operate at 12 Mbit/s (full speed) and 2.0 compiliant, but it's little hard to find chip with 480 Mbits/s. So, is anybody knows such a chip?
power management chip is a prospective ic now.i am a beginner,who tell me what difference between regulator and converter?
Hi there. How can I build one 10 bits A/D converter from two 5 bits Flash AD converter ?
Take a look at this USB-to-Parallel converter: Let's hope it's suitable for your project .. Regards, IanP
1) Try using a Stepper Motor to get direction (use a reference then count the steps taken to settle down) 2) Use a DC motor to get speed (A to d converter)
PWM also can be used to create a buck converter

Can U provide your circuit diagram? I need the same DC DC converter
Hi all, I'm designing a PIC32 based USB oscilloscope. I need a dual supply for the opamps as it simplifies input impedance and level shifting. I selected a unregulated +5V to +/-5V DC to DC converter (needs to be isolated so this limits my choices here) and then I was either going to use +/-3V LDOs in front of this to provide the supply for the
Design for boost converter Hi Im designing a 10-18V SMPS boost converter switching at 35-70Khz and I am not entirely sure on how to select the inductor size. Do I use V = L x di/dt ? where t would be t-on of the power switch and Vo would be (20VDC/5Amp ? Would I plug in values for the inductor and choose for the best di? If so what i
Hi, How do I modify this circuit to work with maximun 38400 baud instead of 9600 baud? The idea is to interface an YAESU FT-897D with Ham Radio DeLuxe rig control software. 68240 Original idea and project by IK2BCP. Thanks, Fernando - PU2PLL
Hi I wanted to know if there is any relation between the Gain factor of coupled inductor boost converter, Coupling coefficient(K), Loading and Magnetising inductance values. ie The gain of coupled inductor boost converter is given as Gv=1+N*D/(1-D) . N being turns ratio.(Here coupling factor is missing) Now if assume N=4,D=0.5,and K=0.95
Feedback regulation is more complicated in a boost converter (as compared to a buck converter). The stepped-up voltage is less directly related to what happens in the first section of the converter. Say you want to step up 9V to 100 V. You do not have 100 V available for a feedback reference V. Therefore you must ensure the (...)

how do you use solder paste? I have to solder some sensitive small components so would it be a good to use the paste instead of reg. solder?
The quantization noise is spread across the frequency range from 0 to the sampling frequency. If you sample twice as much, the qunatization noise density is half. It is to your advantage to sample much higher than the Nyquist frequency. If you do not want to carry the high data rate further in the system, you can low pass filter using more bits
Hello buddy, How can I design a system w/ LVPECL I/O by CMOS 0.18um (TSMC) process, 1.8V rail? or I just can use 3.3V supply that is really a 0.35um process?

what is your source? maybe u can try with dc-dc converter
100 kW is not "extremely high" powr level. IRG4PH50U (in the TO247 case) can deliver up to 50 kW in a step-down DC-DC converter
Hi all, I would like to know about your TIP or Technic in ferrite bead selection Thank you
The typical ADc sample ratios are seldom higher then 1 megaSPS. What are the highest speeds available by now for the ADCs on-board (DSP & mPCs from different manufactures)? What type of data conversion these devices utilise? How those high speeds of data-sampling - up to 1-2 GigaSPS are realisid in Tektronix scopes for instance?
Hello, I want to use a GSM module with a mp3 reader hardware. I have no experience with GSM module. Most of GSM modules have an UART interface. I'd like to know if I can get the gsm compressed data voice to send it to the mp3 recorder in order to record it. It would be nice too if i can read mp3 file and send it by GSM. thank you for your he

Hi all I need sites that like I can download books but I need Mathematical books. regard
H ehe eh eheh e ! the Simpler way than . . . . . 1. R to Voltage: Why can't you use the formula: V = I * R (if I = constant) (you should use the IC as REF02, . . . . to reference current). 2. Voltage to voltage converter : This is the DC - DC converter ? if it is right, you should MC34063 ! 3. Temp . to voltage con
