hello there i am new in this forum but i´m planning to stay here for a long time .
i have an issue with proteus, i am trying to simulate a triangule wave using 2 opamps (tl082) one as an integrator and the other as a square wave generator
originally i thought it was a bug from proteus but well i saw on youtube and others source of reference that it should not give anyproblem... after that i tried falstad and it is working with no issue
i am posting an image showing both simulations
can you guys help m find this problem please?, is it telling me that the slew rate is to low for the frequency i want it to work with?
for what purpuse i am doing this triangle generator , well i will use it to compare it with signal from either a ldr or a phototransistor (ofc both signal will be converted to voltage) and generate a pwm to move a pair of dc motors
i was thinking of using a timer 555 but i am working with voltage (as far as i investigate timer 555 pin 5 is for vco and not pwm)
finally , i know there are components like LTC6992 that just work how i want XD. but it is not on sale(?) at the "markets" i am familiar with and buying at digikey well cost too much time
i am uploading the file if there is someone ready to test it please. (as a side note change the extension from .txt to .pdsprj)
and i am sending the link from falstad if you are interested in it too

thanks for your time trying to understand me and love
