If I want to optimize for area, does it make sense to push the sampling clock the higher end?
Assuming SQNR is sufficient, and output sample rate is fixed. If I double Fs, I can shrink integrator Cap by 2x.
Other performances:
- Noise is not changing as R/gm doesn't really change - OSR is 2x but little impact on perf as Q noise is small - excess delay can be compensated
any other item that I missed? Thanks.
