    Hi everyone!My design has a power supply of 1.8V and i want a current source/sink to provide me from -10uA to 10uA but i don't have much experience in electronics and i don't have a clue :confused:...Can anyone help me??
    Thank you for your time.

    Can you explain what this power supply is used for. 1.8V sounds like it is for some microcontroller or similar. Can you provide a bit more info.

    My design has an ASIC with a pad in which i must provide the current i mentioned.I have a regulator,which gives me 1.8V(power supply to the ASIC) and through that pad i told you,current will be drawn or injected,depending on some other parameters (the ASIC internally has a circuit to absorve or provide current to some amplifiers but i don't know further details about it),so i have to provide current from -10uA to 10uA.Does this make any sense now or did i make it worse?
