21. Guarded Limiters Improve High Impedance Sensor Dynamic Range
    Measurement Analog Devices ADA4530-1
    Abstract Measuring the signals from extremely high impedance sensors is a difficult task. These sensors can have output impedances in the Teraohms (1×10 12 Ω). The tiny signal currents coming from sensors such as Faraday cups and ...

22. Learning to like high-voltage op-amp ICs
    Amplifiers Analog Devices AD820AR LT1055 ADHV4702-1
    A lot of the analog-circuit conversation these days is centered on low-power and thus low-voltage considerations. That makes sense for operational amplifiers (op amps), of course, since these basic analog building blocks often serve as a buffer or ...

23. Upper End Limitations of a Duty Cycle
    Supply Analog Devices ADP2370 ADP2441
    Switching regulators use a duty cycle to realize voltage or current feedback control. The duty cycle is the ratio of the turn-on time (T ON ) to the complete cycle length, the turn-off time (T OFF ) plus on time, and defines a simple relationship ...

24. What Actually Is a Hot Loop?
    Supply Analog Devices LT8609S
    Electromagnetic compatibility and oftentimes PCB trace routing are key participants in the switching-regulator hot-loop phenomenon. The term hot loop is relevant whenever switching regulators and their electromagnetic compatibility (EMC) are ...

27. Guidelines for Placing the Inductor on a Switch Mode Power Supply Printed Circuit Board
    Printed Circuit Boards (PCB) Supply Analog Devices ADP2360
    Question: Where should the coil go? Answer: Switching regulators for voltage conversion use inductors for temporarily storing energy. These inductors are often very large components and must be positioned in the printed circuit board (PCB) layout ...
