Hi all,
I have heard that it is common in Power Amplifier design for the nonlinearity of one stage to cancel the non-idealities of another stage. For example, one stage may show gain expansion, while the next might show gain compression, and the two effects nullify resulting in linear gain.
Can I get anybody else's perspective on whether this is a good design practice? I'm thinking that although better efficiency may be achieved, the circuit's robustness to process variation may degrade.
thanks, Aaron
