Hi,

I'm looking of some kind of memory like "1 bit memory circuit" but instead of bits i want store voltages.

For better understanding like the "1 bit memory circuit" if I send 1 bit it store and output 1 until reset, so, what i looking for is similar but with voltages, if i send 1 bit with one volt it store and output 1 volt until reset or new bit with voltage.


I don't have any clue...

Any ideas???

Hi,

you want to to store any anloge value? Then look for sample and hold circuits. But it keeps value only for a limited time...

For inifinte time maybe digital pots are useful.
It needs a comparator and some logic. It needs some sampling time for the wiper to adjust. then it has theoretically infinite hold time.

hi,
I already look for sample and hold circuits but i don't find one working diagram

my idea is very similar with the tft pixel
