Hello, for technical reasons I'm looking for a schematic of an Op Amp built with discret components and having GBP over 30 MHz.

Discussion Overview
The discussion revolves around the request for a schematic of an operational amplifier (Op Amp) constructed with discrete components that has a gain-bandwidth product (GBP) exceeding 30 MHz. Participants explore the rationale behind using discrete components versus monolithic ICs, particularly in the context of ESD sensitivity and component replacement.
Discussion Character
- Technical explanation
- Debate/contested
Main Points Raised
- One participant requests a schematic for a discrete Op Amp with a GBP over 30 MHz.
- Another participant questions whether the request is for a class assignment and suggests that discrete construction may not be preferable to monolithic options.
- A participant explains their preference for discrete components due to issues with ESD sensitivity in monolithic ICs, particularly in SMD packaging.
- It is noted that most IC packages include schematics in their datasheets, although some details may be omitted.
- One participant argues that protecting a chip from ESD can be achieved with external diodes, suggesting that designing a discrete Op Amp for the specified bandwidth would be more complex than implementing ESD protection.
Areas of Agreement / Disagreement
Participants express differing views on the necessity and practicality of using discrete components versus monolithic ICs, indicating that multiple competing perspectives remain unresolved.
Contextual Notes
Participants have not reached a consensus on the best approach to address ESD issues or the feasibility of constructing a discrete Op Amp with the desired specifications.
