I'm working on a bioimpedance project.

I want to create a VCCS, based on enhanced howland circuit.

I would like to get a steady current of below 1mAmp.

The current should be stable over wide band of frequencies (1Khz up to 1Mhz)

The current should be stable on wide range of loads (1ohm up to 10Kohm).

The current should be as noise free as possible.

I would like to ask how to designe the circuit for that purpuse.

I've used a circuit which i've taken from a paper from 2012 (attached) but it is not stable at wide frequencies or loads.
