From this paper, it is shown that the input-referred offset contribution from M2b = delta_V_T2b * (gm2/gm1) , gm2=gm3.
This is done as if V2b = 0. (red mark)
But I am not comfortable with this.
Am I missing something here?
As a comparison, for other calculation, e.g., M1a and M4a, the input DC source is grounded. (blue mark).
Then, we can link it with its gm to find the output current.
This I understand.
