Transimpedance Amplifier for (TIA) for nanoAmps

Here is my last achievement.
This is an electronic scheme well filters the hindrances and will greatly reduce the noises.
This will allow to raise sensitivity.
Here is degree of the suppression of some frequencies:
2kHz -75dB
500Hz -58dB
120Hz -100dB
100Hz -106dB
60Hz -123dB
50Hz -129dB
