FAQs
Blood oxygen meters, Part 2: IC implementations
It is now trivial and non-invasive to measure blood-oxygen saturation SpO2, thanks to LEDs, algorithms, and ICs for pulse oximetry — it’s a very long way from having to draw blood and send it out for assessment. Part 1 of this FAQ discussed the principle of the non-invasive, light-based pulse-oximetry systems for reading blood-oxygen saturation […]
Understanding and testing asynchronous logic
Traditionally, computer and instrumentation engineers work with synchronous logic, where a global clock circuit imposes a timing structure to which all circuits down to the components level adhere. In synchronous logic, an autonomous oscillator outputs a square wave that never varies in frequency or amplitude. At the rising edge (sometimes falling edge) a potentially vast […]
Blood oxygen meters, Part 1: Background and principles
It is now trivial and non-invasive to measure blood-oxygen saturation SpO2, thanks to LEDs, algorithms, and ICs for pulse oximetry — and it’s a very long way from having to draw blood and send it out for assessment. Just a few decades ago, determining the vital medical parameter known as blood oxygen level — formally […]
When should you use sealed connectors?
Any time a connector needs to be protected from the environment where it operates, you should consider choosing one of two types of sealed connectors. The two types of sealing available include hermetic sealing, where the contacts are sealed against air and gases; and environmental seals, such as those with an IP or ingress protection […]
Why clean PCBs matter, Part I
Printed circuit boards (PCBs) are essential in modern electronics. Dust and other contaminants are more important to watch out for than ever. As components get smaller, the relative size of contaminants is larger, heat is more of an issue with densely packed circuits on modern ICs, and devices operating at high frequencies (~1 GHz and […]
Working with optical fiber
Optical fiber is actually a waveguide for light and operates in accordance with a principle known as total internal reflection. In contrast to electrical conduction, there is low loss and signals can be conveyed over considerable distances without amplification. Total internal reflection happens when a propagated wave strikes the boundary between two dissimilar materials, provided […]
Why is it vital to include power factor in ac-dc efficiency measurements?
Ron Stull of CUI explains what power factor is, how it affects efficiency calculations and how it is measured With today’s concentration on energy savings, design engineers need to know with increasing accuracy what their ac-dc power converter efficiency is. Measuring the ratio of output power to input power is simple for dc-dc converters, but […]
Quartz crystals and oscillators, Part 2: Advanced crystals
Part 1 of this FAQ established the context for the quartz crystal as the core of an oscillator whether used as a system clock or as a frequency-setting element in a tuning circuit. This part looks at the achievable performance, the factors that affect it, and what can be done for highest performance. Q: What […]
Power-supply overvoltage protection, Part 2: Clamps
Part 1 of this FAQ discussed the context of overvoltage protection and crowbars which provide OVP. This part will look at clamps for OVP use. Q: What does the clamp do? A: A clamp conducts just-enough current to maintain the voltage across it at a safe, desired value when the transient is above the clamp’s […]
