hi all
my voltage booster circuit {http://john111smith.googlepages.com/vbstr.png}
shows the following noise levels:
A: <+-50mv
B:~ +-200mv at 67v output
D:~ 0
OpAmp: OP07 or LM741
How can I reduce noise level at point B to about +-50mv?
Hi All,
I wish you a Merry Christmas and a Happy New Year.
I try to use a PID controller instead of an old hardware vacuum controller. While, a turbo pump decrease pressure; a valve connected to the vacuum chamber, increase pressure.
What is the equation that represents the function of the...

Hi,
How can I set "PID parameters" for the control of the system with the following "power serie" ?
y = 3E-40*x^18.94
X min = 30
X max = 90
PID parameters:
iMax,iMin,
pState,istate,dState,
pGain,iGain,dGain,
MAX,MIN

Hi all,
I going to design a power supply with 6KV / 700uA (<30mv ripple) output and 10 Volts DC input?
its based on push-pull transistor driver for ferrite transformer input and a N stage (diode-capcacitor pump) voltage mltiplier?
How can I calculate capacitance of capacitors & number of...
Hi All,
I engaged with windows 98se installation on usb falsh.
I work to replace pc hdd with a 1 gb flash disk.
Thanks to [mkbt20], boot from usb was successful, but windows 98se setup show some error:
1- when usb flash as drive A; setup say cant install on drive a
2- when usb flash as drive...
