Hi,
All that books just for reference and the opamp still 2 stages. But now i'm finding a circuit at schematic with more than 2 stages (these opamps can be designed for production)
Thanks,
you can refer the book "Frequency Compensation Techniques For Low-Power Operational Amplifiers" by Rudy G.H.Eschauzier and Johan H.Huijsing which can be downloaded in the forum, in the book, the author give some example of multistage opamp design and frequency compensation
