Resistance in the supply rails
01/01/70 00:00
inductor instead of resistor
01/01/70 00:00
yes, and no and I think the theory is flawed
01/01/70 00:00
Spice?
01/01/70 00:00
That would probably help, but ...
01/01/70 00:00
That's what I said
01/01/70 00:00
Not in the gnd path!
01/01/70 00:00
Well ... this normally doesn't work so well, but
01/01/70 00:00
If this scheme is used it would also be well to...
01/01/70 00:00
This does increase the supply impedance
01/01/70 00:00
please clarify with a simple schematic
01/01/70 00:00
the bypass cap\'s always go between Vcc and Gnd
01/01/70 00:00
Which Vcc, Which gnd
01/01/70 00:00
There's a cap on either side of the resistor(s)
01/01/70 00:00
is it
01/01/70 00:00
Not quite ...
01/01/70 00:00
don't use a resistor in the GND connection
01/01/70 00:00
What >good reason< could this be??
01/01/70 00:00
What good reason could this be??
01/01/70 00:00
Using a resistor in the GND connection...
01/01/70 00:00
How would that come to pass?
01/01/70 00:00
Why should I insert a resistor in the GND line??
01/01/70 00:00
Seldom andonly if it is of benefit
01/01/70 00:00
No disagree, but ...
01/01/70 00:00
The regulator can't pull the Vcc down
01/01/70 00:00
This has nothing to do with imbalance!
01/01/70 00:00
Kai, I don\'t disagree ...
01/01/70 00:00
Again, do not add any impedance in the GND line
01/01/70 00:00
tantalum capacitor across the MAX232 power pins
01/01/70 00:00
It's a matter of careful choice
01/01/70 00:00
Yes they does
