    pid equation????????????

    Co=kp*e(t)+Ki*int(0-t)[e(t)]dt+Kd*d/dt(t) MCU is using In practically we are using our pid in temperature control,but it not giving the 100% control out put,auto tuning is done by ZNFD method

    voltage signal conditioning

    hi i need to make nine 0-1v from nine seperate milli volt ranges,while i am doing this one, facing a big problam that my pcb getting very big size,my device require 90x90 industrial standard size and it also requires somany span and zero adjustment,i used here LM741 opamp for signal conditioning...
