Figure 1: EMI immunity of op amps affects system operation
There are growing requirements in many industries for sensing technologies for measuring and control instruments, or for managing small signals. Op amps connect the sensor to the rest of the system.
However, today’s systems have much higher component densities, leading to increased noise levels. Installi

Figure 1. Closed-loop motor control feedback system
Motor rotation information such as position, speed, and direction must be accurate in order to produce precise drivers and controllers across a wide variety of emerging applications—for example, in pick-and-place machines that mount microscopic components in the limited PCB area. Recently, motor controls have be

Figure 1: Voltage modulation and phase current at 20 kHz with 500 ns dead time
So far, silicon-based power devices have been dominant in the inverter electronics, but today their performance is nearing their theoretical limits. There is an increasing need for higher power density. Gallium nitride (GaN) transistors and ICs have the best attributes to satisfy these needs.
The superior

Figure 1: Technician adjusting connections at wiring closet
Connecting sensors and actuators to a process controller at the wiring cabinet is still a manually intensive and sometimes frustrating task. For example, if a process modification means a valve being driven by a Digital Output (DO) voltage must be changed to one using a 4-20mA Analog Output (AO) current, a technician mu

As we head to the end of the year, it is often time to look back and reflect on how things have changed. This month, and very close to where I live, leaders from around the world will be doing their own retrospective analysis on how they are progressing towards meeting the climate change goals they had previously se
