    Hi everyone,

    I am trying to make a current-feedback IA on Cadence, using a design given in a paper, but I am getting errors. Do I need to include a source follower at the output to lower the output resistance? Or include a buffer? How do you make a buffer using CMOS technology? Any help or ideas would be really appreciated!!
    I have included a screenshot of my circuit and testbench:

    This is the error I am currently getting:
    p, li { white-space: pre-wrap; }

    ERROR (ADEXL-5025): Preparation to run the simulation is failed for the run Interactive.1, point 1, test ia:IApapertestbench:1, received error:

    Error:

    ------------------------------

    Error while preparing to run the simulation.

    Netlist directory "/home/uceembw/current feedback IA/Sim/ia/IApapertestbench/adexl/results/data/Interactive.1/1/ia:IApapertestbench:1/netlist" does not exist

    For details open log: /home/uceembw/current feedback IA/logs_uceemjw/logs0/Job1.log for the point: (1 1)

    Thank you!

    Best wishes,
