I am designing the transimpedance amplifier with OPA2846.
I have a big concern for the noise as my light output is extremely weak say 10nA.
So my layout design should be extra clean.
May I have gerber file sample for that OPA2846 for transimpedance amplifier design.
For the power supply, I design switching mode power supply (as we use battery) and then LDO 5V output for power supply noise reduction.
What do I need to take care in terms of layout or in terms of power supply for that noise concern?
