Circuit designers have a blind spot when it comes to positive feedback. We’re okay with positive feedback in things like latches and oscillators. Those aren’t supposed to be stable. But for normal control loops with positive feedback, we either believe it can’t be done or believe it shouldn’t be done. Most textbooks on circuits, and even on control theory, tend to dismiss the topic with a few sentences about growing exponentials and certain death (see Figure 1 ). Where did these mental roadblocks come from? Despite all the bad press, positive feedback is far more common—and useful—than you might think. So, stop cowering under your desk and let’s face this like adults.

Digitally assisted analog circuits are becoming the mainstream solution in modern CMOS processes as they improve circuit performance and reduce implementation costs [1] . The most representative example of digital assistance is the compensation of the nonlinearity of an analog block, which is done by applying the digital inverse of the nonlinearity at the output. However, as the digital inverse is not known a priori, it has to be estimated, and the estimation needs to adapt in the background to the environmental conditions. This is typically accomplished by relying on adaptive filtering, i.e., by closing a system-identification engine in feedback that injects a modulation at the input of the nonlinear block. This article, after reviewing the basics of both PLLs and adaptive filters, will explore the most significant calibrations adopted in PLLs.

As of 2021, 537 million adults are living with diabetes: that is one person in 10. This number is expected to rise by 20% to 643 million by 2030 [1] . The rate at which the disease is spreading among the world’s population requires a new approach to management and care, and most importantly prevention. The prevalence of diabetes has seen health-care costs rise significantly over the past decade, further exasperating the issue. For example, in the United States the lifetime cost for managing one person with type one diabetes is approximately US ${$}$ 1.5 million, totaling a staggering US ${$}$ 1.5 trillion for all diabetic patients in the United States [2] . Fortunately, during the last decade there have been significant advances in diabetes prevention and management technologies, including continuous glucose monitors (CGMs), as introduced in our pilot article in our previous issue. Many doctors are now advocating for those who have not yet been diagnosed with diabetes, but may be at high risk or borderline, to start using CGMs for disease prevention, which ultimately will help save lives and health-care costs. CGMs are biosensors that measure glucose values in the subcutaneous space via a sensor that includes wireless transmission of data to a receiving device, such as a smartphone. In this article we will dive into the world of CGMs, beginning with what the system should include and relevant design constraints. We begin at the system level.
