摘要

A third-order complex delta-sigma modulation (CDSM) structure with cross-coupling paths is proposed and analysed. Although the conventional CDSM can reduce circuits complexity in digital transmitter systems, it suffers from other shortcomings like increasing algorithm complexity. This structure imports cross-coupling paths both at output and interstage, which realises decorrelation between zeros a...
