Introduced zero to cancel cavity pole. Mostly final circuit. |

After discussion with Johannes, I added a zero near the cavity pole to neutralize its effect at higher frequencies. I also replaced the passive high frequency boost with an active one in stage 3. Attached is the new circuit schematic (Mostly final one as it looks good). Also attached are open loop transfer function from LTSpice.
Next steps are to do noise analysis and individual opamp stability analysis in LISO one last time. |
