Thanks.
 

Re: Question Inverter

while power on the output impedance of the inverter is zero since it is supposed to maintain its voltage value irrespective of the amount of current it sinks or sources.....

Re: Question Inverter

If is low impedence, this means the voltage level of output during power on is zero.

Right?
 

Re: Question Inverter

how r u coming to that conclusion..
 

Re: Question Inverter

if the impedence of output is zero, it doesn't matter how much the corrent is going to flow, since the V = Current * impedance.

if impedence = 0.

then V = 0.

right?
 

Re: Question Inverter

what we are talking about is the output impedance of the circuit and output impedance is pictured as being connected in series with the output.... since in our case the circuit output impedance is zero the drop from the output to the circuit to the output that we get is zero, no matter how much current flows..... it doesn't mean the circuits output will be zero...

Regards.....

Re: Question Inverter

EDA_81hg,
You might want to consider this way:
If the out put is high, say 3V, and output impedance is zero,
and if you put 1 kohm load, current will be 3mA.
If you put zero ohm load, current will be infinity.
Hope this helps.
S.H.

Re: Question Inverter

If I use RC circuit to enlarge the power rising time to the inverter and the input rising time to inverter follows the I/O rising timing set by FPAG without RC power delay.

What is the result?

Some guy said if use this way the inverter can be damaged.

Thanks.

Added after 1 minutes:

Thank you all so much.

I understand it.
 

Re: Question Inverter

can you please specify what FPAG is... i dont remember having heard any term like that....
