    System trade-offs for high- and low-side current measurements

    Measuring current may sound like a simple task, but it is not as easy as it sounds. Current can’t be sensed directly; however, it is related to other measureable parameters that you can sense directly, such as voltage and magnetic field density. In general, there are two ways to measure current. The first is by measuring the magnetic field...

    How to bias PIR sensors to prolong battery life in wireless motion detectors

    Wireless, battery-operated, passive infrared (PIR) motion detectors (represented in Figure 1) are gaining popularity in monitoring systems for smart buildings . In these systems, for a single CR2032 coin-cell battery to power the entire circuit close to the circuit’s lifetime, both the PIR sensor and related analog front end (AFE) must have current...
