Continuous-time ?S modulators using distributed resonators

We derive a method for using distributed resonators in modulators and demonstrate these modulators have several advantages over existing modulator architectures. Like continuous-time (CT) modulators, the proposed modulators do not require a high-precision track-and-hold, and additionally can take advantage of the high- of distributed resonators. Like discrete-time modulators, the proposed modulators are relatively insensitive to feedback loop delays and can subsample. We present simulations of several types of these modulators and examine the challenges in their design.
