his educational session is composed on two parts. In the first part, we will cover the topic of universal sensor design introducing a method for the design of any sensor acquisition chain is anyhow related to a few constraints (time, information, and power consumption). The method will show how framing the design along a few variables can enhance the overall performance and reduce the design time. We will also show how to optimize the segmentation and quantization of the sensing acquisition chain to maximize the resolution and the time response of the overall system. In the second part, we will dive deeper and try to build an intuitive view of sampling and one-bit quantization on the specific topic of signal-noise interaction. Furthermore, we will see how this more intuitive and simpler view can help addressing problems that for an exact solution would require high-order math (like special functions) and provide approximate solutions which are useful in many applications, like determine the quantizer gain in single-bit delta-sigma converter or dynamic-element matching.
