A delay‐based noise cancelling sturdy multi‐stage noise shaping (MASH) structure that cancels the first‐stage quantisation error is presented. Thus, a smaller number of bits can be used for the first‐stage quantiser without degrading the overall performance. In addition, the proposed structure improves stability with respect to maximum applicable input by removing the first‐stage quantisation error from the first loop.
