hi
I have a question:
while designing the decoupling cap required for a ckt. why do we use a cap which has voltage rating twice the input voltage?
can anyone of you help to share teh reasoning behind that?
thanks and regards

hi,
as mentioned of a project, we were trying to implement the peak detector using the below circuitry for4 AC circuit. But we are NOT able to get teh constant peak voltage. can any one pls help me to identify the mistake of this circuit?

CURRENT AMPLIFIER
hi
I am looking for CURRENT AMPLIFIER, which can produce constant amplitude irrespective of input voltage amplitude
can anyone help me to get good circuit/IC based on teh same?
regards,

hi
I was talking about an amplifier which can produce constant amplitude, irrespective of the input voltage amplitude
Somethinh like CURRENT AMPLIFIER. If anyone has any data/circuit on the same. can you pls help me to get some documents on the same?
in google, I am not able to correct;y find...
can anyone pls suggest a current amplifier circuitry?
also, is it possible to keep the amplify and keep the voltage of current amplifier constant?
what i am looking at now is an amplifier which can give 40 Vp-p signal
hi Audioguru: can you pls provide me details regarding the automatic level...
piezo elctric crystal
hi,
i have a doubt.
when a piezoelectric crystal degrades, ideal what parameter of the crystal is causing degradation?
Is it electrostatic cap of piezo changing? can anyone pls pass on any interesting material on piezo?

Filter circuit for audio
Hi all,
I am designing one circuit (as a hobby) to amplify the audio of fan. I expect the sound signal will be around 0-8kHz. But when I feed this signal as such to loudspeaker, I am hearing some trebles, noises etc...
So we need a filter... my questions are like this...

hi
can I get a ebook of Integrity Issues and Printed Circuit Board Design by ?[/color][/b] Douglas Brooks?[/color][/b]
Where can I get to improve my knowledge in PCB design, SI ?
thanks
Hi friends,
How the decoupling capacitors values are arrived at?
If for example, if they need 10 no of 22uF,0805 capacitors, and 2 no of 330uF bulk capacitors. My doubts are:-
1. How did they arrived at the capacitor values?
2. no of capacitors? like can I replace 10 no of 22uF capacitors...
Hi,
Have you ever tried deleting a part in heterogenous package? Then can you please help me.
I was trying to create a schematic symbol for heterogenous part. I need to delete a part in heterogenous package and tried to delete the part by selecting it in package view. But OrCAD is getting...

Thank You Hook.
I have some more doubts in memory. Posted in this link:-
Actually I am struggling to get knowledge in SSTL logic used in DDR. Can you help me if you have any good reading material?
I shall be greatful to you, if so.
Thanks once again,
sita
