hy there, i'm new to electronic and need some help. i want to use a comparator to measure some voltage in micro or nano dimensions, and dont have an oscilloscope. i cannot get the information i want from the data sheets. does any one know a micro controller that can compare micro volts or even better help me understanding these sheets where to look etc
thanks in advance

Generally we talk of mV (milli Volt), uV (micro Volt) and pV (pico Volt) but not nano Volt.

So you want to compare two voltages down in the microVolt region using a comparator IC (chip) or with a microcontroller?

Some more descriptive information is required. Such as data sheets, device types, circut schematic, application etc.

P.S. If you wanna get serious about electronics then an oscilloscope is pretty much a necessity.

 

all i need is the name of a cheap chip that can compare two voltage in uV region or even better, can most of these chips do that, and cannot afford an oscilloscope for the moment, will have to do with out

Generally comparing voltages in the μV region is dicey. Can you amplify the signals before comparison?

 

i was already thinking about it, but would prefer to avoid this solution
