2604.01439 Oversampled ADCs with Noise Shaping Achieve 16-Bit Effective Resolution Using Only 8-Bit Converters in Software-Defined Radio
Oversampled ADCs with noise shaping achieve 16-bit effective resolution (ENOB) using only 8-bit converters in software-defined radio. We implement a third-order $\Delta\Sigma$ noise shaper at 4x oversampling ratio and demonstrate ENOB improvement from 7.
