Attitude and heading reference system (AHRS) is a device that utilizes MEMS inertial sensors (accelerometers, gyroscopes) and magnetometers, combined with advanced sensor fusion algorithms (most commonly Kalman filtering and its variants), to calculate real-time attitude information (pitch angle, r...

Inrush current is a transient, high current generated when a power supply or device is powered on. In our power supplies and electronic systems, inrush current is undesirable because it can cause device overstress and damage. Buck switching power supply circuits use a soft-start circuit to control t...

  FOG North Finder is a precision instrument that utilizes the Sagnac effect of fiber optic gyroscopes to accurately and autonomously determine the true north direction (geographic North Pole direction). It does not rely on external references such as GPS, astronomical observations, or known re...

  The application of MEMS inertial measurement units (IMU) in the industrial field mainly focuses on high-precision motion control, equipment monitoring, and automated production. Choosing a suitable MEMS IMU in the industrial application field requires comprehensive consideration of accuracy,...

To ensure signal routing quality and prevent crosstalk during PCB design, we maintain a spacing of three times the line width between signal traces. As shown in Figure 1, this spacing refers to the center-to-center spacing of the traces. Because line width is expressed in English as "width," this ru...

Tilt angle sensors play a crucial role in bridge monitoring, mainly used to measure changes in the tilt angle of bridge structures or their key components relative to the direction of gravity. These minor changes are often important indicators of the health status, load response, foundation settleme...

When designing high-speed or high-frequency PCBs, electronics engineers use the 20H principle to meet EMI standards and reduce electromagnetic radiation. This principle requires the power plane to be set back 20H relative to the ground plane, where H represents the distance between the power plane a...

  One-minute quick read The Fiber Optical Strapdown Inertial Navigation System (FOG-SINS) uses fiber optic gyroscopes (FOGs) and accelerometers to form a solid-state inertial measurement unit (IMU), which calculates the motion parameters of the carrier in real time through a strapdown algorith...

Sensors and instruments all have an operating voltage range, and only within this voltage range can the system operate stably and reliably. We know that the high-voltage threshold can be controlled by an overvoltage protection circuit, but how is the low-voltage threshold defined? Power supplies typ...

  Vibration detection of industrial equipment has become a core component of predictive maintenance. The changes in vibration signals can reflect potential faults such as bearing wear, abnormal gear meshing, and rotor imbalance. MEMS (Micro Electro Mechanical Systems) sensors, with their advant...

Figure 1 BUC power supply Typically, when designing an asynchronous buck power supply, a bootstrap capacitor is connected between the chip's SW and BOOT pins, such as C1 in Figure 1. The bootstrap capacitor utilizes the characteristic that the voltage across the capacitor cannot change suddenly. Whe...
