Technical Description
This invention uses N-path chopping and FIR feedback DAC to enable low-frequency chopping while creating spectral nulls that suppress aliased noise, preserving high SNDR without complex FIR DACs or high-speed chopping that hurts linearity.
Problems Addressed
- Low-Bandwidth Noise
- Chopping Aliasing
- Signal Band Degradation
- OTA Linearity Loss
- Complex FIR DACs
- STF Peaking Issues
