HI, I have a level 49 MOSFET model for HSPICE and I want to use it i
LSPICE. How I do it, step by step? I mean I'm new in LTSPICE and I've n
idea how to modify mos parameters. Thank you very much, this is the model

There were three men left.
Two believed in one book but disagreed about its meaning.
One used to belong to others who believed in a different book but the others
disagreed about its meaning.

Alright, I have been trying for the past couple of months to create
this LED bar graph--the premise for the circuit was this: when the
circuit was turned on, it would light up a 2x5 matrix of LED's in
sequence, where after about 4 seconds, all of the LED's would be lit.

Cheers all.Niece to have you. I want to acquire some knowledge on the
above subject. Can any one aquaint me with literature or website on the
application to the following subject matters : aerospace,
satellite,fractionating column,nuclear station process and any other

Hi, all,
I am looking for electrolytic capacitor with lifetime 5,000 hours and
case size 8mm.
Could you tell me a vender of it.

      Finally, I decide to use LM386 for my audio amplifier, I think
it is cheap and enough, am I right?
One thing I not very understand is:
why some circuits of application note has no nagetive feedback? and it

I have a schmidt hub generator and I would like to use it to power a 3W
Luxeon Star, if possible two of them.
The Schmidt hub generator is a AC generator that is built into the
centre of a front bicycle wheel.  As the bike moves power is made.  It

Im starting a new design.  Typically I've always used a codec to bring audio
in/out of the system.
The micro I'm looking at using has an onboard ADC and a PWM.  It would be
very exciting if the PWM could be used for the DAC functionality.

I am working on a GPS data logger working on 3.3V
I'm pretty much done with all the digital design but one thing is still
missing and I'm not familiar enough with analog electronics to do it.
I would like the device to be able to get power supply from both 3-4 AA

             TI Audio dac 1742, any pin to pin chip?
Best regards,
Boki.

Induction heater project.  It's looking like I need maybe 4 x 50A 600V
highspeed IGBTs, or a 100A single phase module.  If someone has some
low-cost suggestions, I'd be glad to hear them.
I still haven't produced the formulas for peak current in terms of supply

Hello, I would like to know how to estimate the noise on cmos image
sensors. We have a custom cmos image sensor designed/ manufactured by a
company and we have designed a proto board for hosting the cmos image
sensor with A/D converter, clock, power supply etc which is interfaced

I am not an RF engineer (limited knowledge - amateur radio days). I
would like to shift a signal (its a doppler return signal) from the 0
Hz - 160 MHz band  to something lower in value so that I can reduce my
sampling rate. If the frequencies of interest were lets say

Hi, does anyone know where I can get a formal Backus-Naur style syntax
and/or grammar definition for any of the various SPICEs out there?
Specifically, hspice, pspice, or berkeley spice.  What is the
difference from a grammar/syntax perspective?

Hello everyone, I'd like your thoughts please.
I'm going to design a garden lighting system that will control a
number of 12V AC GU5.3 dichroic lamps. I want to fade up/down a number
of these lamps and I'm trying to think of the best way to do it. At
