GFCIs detect hazardous current paths to ground and ground-to-neutral faults. They are relatively simple but have circuit details that can be tricky to figure out. In this short video, we go through the main functions of the main GFCI controller chip and the sensors that let it detect fault currents of various natures. … [Read More...]

FAQs
What are MRAMs?
MRAM, Magneto-Resistive Random Access Memory, is a type of non-volatile memory (NVM) capable of holding saved data even if the power is down or the power is accidentally cut off. MRAM — also called Magnetic RAM — is not new. It has been in the market for more than two decades, but there have been several […]
Microwave/Millimeter Wave interconnects, Part 2: Connectors and cable assemblies
Part 1 of this FAQ look at the coaxial cables used in microwave/millimeter wave interconnects and cable assemblies. But a cable alone is only half a solution; the cable must be terminated with connectors. Often, the completed cable/interconnect assembly is also called a cable, but this is generally not an ambiguous situation (but it may […]
Wireless charging, Part 2: Implementation
Part 1 of this FAQ looked at the overall context of wireless charging of personal devices. This part looks in more detail at the approaches to wireless charging and the implementation specifics. Q: What approaches are available for wireless charging? A: There are three basic topologies: single-coil inductive, multi-coil inductive, and resonant. Q: What are […]
Wireless charging, Part 1: Context
Wireless charging of devices is a hot and growing area. This FAQ explores the rationale and options for implementing this form of energy transfer, storage, and charging. Q: What is wireless charging? A: It consists of two functions which are closely linked. The first is the transmission of electricals power wirelessly from a transmitting source […]
Microwave/Millimeter Wave interconnects, Part 1: Coaxial cables
Cables, connectors, and interconnects (cable assemblies) are essential yet often underappreciated parts of a system design. Even though the popular meme is “everything is going wireless” thus eliminating the need for cable assemblies, the reality is that these assemblies are critical both within circuits at either end of a wireless link, or as the only […]
Considerations in PCB layout guidelines
A Printed Circuit Board (PCB) layout, in its most basic form, is a means to transfer a circuit from a breadboard to a more stable and permanent physical form. Whereas entire books and college coursework have been dedicated to PCB layout, what follows is a short overview of what to consider when making a PCB. […]
An introduction to audio jack switches and schematics
Standard 2.5 mm or 3.5 mm audio jacks are found in a huge variety of consumer and professional audio products. Widely recognized, easy to use and simple in concept, they can be applied in many ways to enhance convenience for users and manage various features and functions of a product that are not necessarily related […]
Measuring comparator performance; The difference between comparators and op amps
A comparator, as its name suggests, compares two voltages or currents and determines which is higher. The usual implementation is with two inputs for the voltages that are to be compared and a single output that by mean of a logic high or logic low state indicates the higher of the two inputs. Typically, a […]
Reducing ringing or reflections by controlling impedance lines
What is a controlled impedance line? For one thing, the term has to do with Printed Circuit Board (PCB) traces and layouts, which get more complex with higher frequency signals. Generally, you need not worry much about controlling impedance in traces unless you are working with signals at or above 50 MHz. However, most of […]
