Here is a detailed view of reverse polarity protection circuits for safeguarding battery-connected automotive systems.

Impulse relay turns on with an electrical impulse at the control input and turns off again with another impulse.

New multi-GHz oscillators (XOs) and jitter attenuators bring timing chips into the digital domain by employing CMOS technology.

Most electrical and electronic devices today require a method to detect tampering. In many cases, it could mean that the door of a device has been opened. This post will share some tamper detection ...

The first installment of this two-part series focused on debugging brushed-DC motor systems. Now the second installment will share some tips for stepper motor systems and provide general bench testing ...

Sensors are getting smarter by integrating sensing technology with embedded microcontrollers, software, and artificial intelligence (AI) that runs inside the sensor itself. Here, software solutions ...

Our fundamental passive and inherently analog components—resistors, capacitors, and inductors—are so conceptually simple and easy to describe that we often don’t fully articulate or appreciate the ...

When tasked with a current sensing requirement, designers typically look first to using dedicated resistors designed for this task. Occasionally though there is the temptation to consider sensing ...

In operational amplifier stability, one rule of thumb is to allow 45 degrees of phase margin. Other design guidelines state that 60 degrees is best; still others say that 30 degrees is sufficient.

What’s a field-programmable analog array (FPAA), and how does it work? Dr. Jennifer Hasler, who carried out pioneering work on FPAAs at Georgia Tech, explains this analog device’s anatomy and workings ...

There are many secondary functions associated with designing an electrocardiogram (ECG) signal chain, but one of the most important might be the most underrated: making sure that the electrodes are ...

Along with duct tape and nylon cable ties, heat shrink tubing is an essential element in the engineer’s toolkit as well as manufacturing, production, and repair. It’s used for covering and protecting ...
