i have drawn the final cct using PROTEUS 7 professional software and when i run the simulation there are some errors that i cant find the solution..i attached the circuit and the simulation error if you know whats the problem please..
i set up the amplifier with G=7, after the right leg driver with G=1M/24.after the AD620 is a high pass filter Fc=0.03Hz with voltage follower G=1.after is the low pass filter Fc=100Hz and a non-inverting amplifier of G=144. so i have overall gain = 1008..but i cant understand why when i run the simulation it fails.
can you help me please
