OPA2333: TI Precision Designs"High-Side Voltage-to-Current (V-I) Converter" how to achieve 1M bandwidth

Part Number: OPA2333

Hi Team,

 I recently read the article(TI Precision Designs: Verified Design
High-Side Voltage-to-Current (V-I) Converter and have some questions about how to achieve 1M bandwidth.

Several op-amps with higher bandwidth are mentioned in the article, and some design suggestions are also provided.  I tried to replace the op-amp or zero pole compensation, but I couldn't make the bandwidth 1M. Now I am confused, can you give me some directional guidance on the logic to solve the problem or how to design an ideal 1M bandwidth?

   Any help appreciated! Thanks!
