https://ieeexplore.ieee.org/abstract/document/9697325 - Dual Stage CMOS Operational Amplifier Design in Sky-Water 130nm Technology -- Someone want to review that and provide a summary?

I think there’s a typo here. Pre-parasitics they’re getting 20MHz but it increases after?

Pre-layout simulations of OPAMP gives 62dB of voltage gain with Unity gain bandwidth of 20MHz. Post-layout simulations were carried out using open source MAGIC tool and Ngspice. Post-layout simulations of OPAMP gives 55dB of voltage gain with Unity gain bandwidth of 120MHz with output slew rate of 38 V/µs

@User Is it possible to share the PDF? I cannot access the it via ieee.
