Current Source Topology

Good Morning,

My name is Sang Yun Bang, and I am a graduate research assistant at New York University.

We are developing bio-electronics for the research. Especially, in our all-in-one measurement PCB board project, we are facing difficulties on bi-directional current source topology. The component of LTC6082 has been used for the previous version. However, since we are targeting 0 to 300nA with the resolution of 1 nA, the topology was unstable to implement on our PCB board.

I would like to have the recommendation from the industries' expert and modify our design for the next version.

I will really appreciate any help and suggestion

  • Hi Sang Yun Bang,

    Apologies if we missed this thread.

    How are you progressing on your design?

    Are you limited with this circuit configuration?

    What do you mean  by "the topology was unstable to implement on our PCB board"

    Can you check the CN0151 particularly figure 3 and let me us know if this gonna work in your applications.

    Best regards,

    Emman
