If anyone know pls tell me in Gain bandwidth product, gain in what manner (dB or voltage gain (Vo/Vi)) ?
Gain Bandwidth Product: Voltage & dB Gain Explained
Click For Summary
Discussion Overview
The discussion revolves around the Gain Bandwidth Product (GBWP), specifically addressing whether gain should be expressed in decibels (dB) or as a voltage gain (Vo/Vi). Participants explore the implications of these different representations and their relevance to the GBWP calculation.
Discussion Character
- Debate/contested
Main Points Raised
- One participant asks whether the gain in the Gain Bandwidth Product should be expressed in dB or as voltage gain (Vo/Vi).
- Another participant asserts that the gain should be in voltage gain (Vo/Vi) multiplied by bandwidth in MHz.
- A third participant notes that dB values should not be multiplied or divided, indicating that the only permissible operations are addition and subtraction.
- This participant also mentions that since the GBWP units are in Hz, the gain should be considered unitless (Volt/Volt).
Areas of Agreement / Disagreement
Participants express differing views on whether gain should be represented in dB or as voltage gain, indicating that the discussion remains unresolved with competing perspectives.
Contextual Notes
There are limitations regarding the definitions of gain and the operations applicable to dB quantities, which remain unresolved in the discussion.
