PCB123
If have or can find this version of pcb 123
SAVE IT USE IT BECAUSE
it netlists out and it creates BOM's
and it prints perfect scale and in inverse for
toner transfer protoyping method
these tools are an excelant place to learn real schematic Capture and PCB Layout
they have a...
ofdm blocks
think standard QPSK modem blocks
Tx and Rx
and then on the output of the QPSK_Tx feed a FFT module
and to recieve
come in through an inverse FFT module then into a
QPSK_Rx module
of course you should have some sort of
Forward Error Correction Like Reed Soloman
and you need to...
Electric bike
man
I had a dream for a larger motorcycle
using some OTC Lithium Ion batteries that are
designed for a rechargeable lawnmower
a locking clutch lever to engage the cells with a mechanical switch when its ride time
and and motor controller
I never worked out the charging...
you might want to use a nation semiconductor
simple switcher
they have online cad that lets you input your:
in voltage
out voltage and current requirement and desired ripple performance
it will pic the part, and components etc
a linear regulator is not a good idea going from 19v down to 5...
tell us exactly what you are trying to control
example
lets say you are doing a lab supply with digitally controlled
output voltage and current limiting
then you would simply follow the application note for the switching power supply controller IC and use a DAC's or a digital pot to set the...
The solution must not be put down the drain because of residual copper ions left in it. To make it safe for disposal, you can add sodium carbonate (washing soda) or sodium hydroxide to it to neutralize it, until the pH value goes up to between 7.0 and 8.0, testing it with indicator paper...
so how much faith can one put in their simulator
because with SImetrix
this does function
Thank you
I will try your suggestions and run the simulations
the PFETS were ordered yesterday and the rest of the circuit is benched
with feedback held at ground just to scope the waveforms at the...
if this is home work I cant answer it for you
if you are targeting an FPGA perhaps ..
there are DLL (Delay Lock Loop) modules that you can instantiate
giving 2x 4x etc ... clocks
really your gonna want to use a transformer or the "floating gate driver IC"
that are Quote " readily available and out there "
what the IC's are doing is simple
they employ a switched capacitor voltage generator...
that creates a floating dc supply you can bias against the Source .
with a...
my end goal is 50 volts at 12 amps for a class-D audio application
I would like avoid any heavy Iron and Copper in the whole design.
so I was thinking of using one of Vicors FARM modules that cleanly filter the AC in and
( possibly are doing sync rectification )
but anyway they put out a 400...
