摘要：

Using an auxiliary quantizer before unity-STF SDM, a novel 3rd-order dual-quantizer SDM with extended dynamic range is presented. With hybrid distributed feedback & feedforward paths and an internal feedforward path, a novel low-distortion 3rd-order SDM with simple adder before quantizer is proposed as the unity-STF SDM. Simulations show their perfect immunity to non-idealities.
