    Oscilloscope cursors complement other measurement tools

    Most oscilloscopes these days offer from 25 to 50 automated basic measurements with optional measurements for specialized analysis running close to 100. With all this measurement horsepower available it may seem somewhat archaic to retain the oscilloscope’s original measurement tools of screen graticules and cursors. But these original measurement tools are hardly outdated.

    Variable gain superbal circuit preserves CMRR

    The superbal circuit will be familiar to anyone involved in balanced signal transmission [1]; it is a differential amplifier which presents identical input impedances to both legs of a balanced line. Balanced loading is a necessity for the switching systems used in some audio mixing consoles, for example, to ensure signal balance and common mode rejection ratio (CMRR) are always maintained.

    7 Ways to Quickly Judge the Quality of Your Printed Circuit Board Design

    Although it really takes an expert in PCB design to do a proper full review, there are ways to quickly judge the quality of a PCB design.

    The Power-Supply Conundrum: Make or Buy?

    Sponsored by Digi-Key and CUI: For today’s power designers, oftentimes the complexity of meeting regulatory standards makes the choice an easy one.

    For many if not most electronic engineers, the power supply of your product isn’t your primary focus. Your priority concerns are the features, specifications, capabilities, cost, and performance of that product. Nonetheless, all designs need a power supply.

    At some point you must get around to specifying your power needs and deciding how to meet them. The big decision is whether you make the power supply yourself or buy one? That choice has become easier over the years: These days, buying an off-the-shelf power supply is an increasingly good decision.

    Circuits protect outputs against overvoltage

    In test-and-measurement applications, you must provide overvoltage protection for the output terminals of amplifiers, power supplies, and similar components. The conventional way to accomplish this task is to add series resistors with the output node along with the clamping diodes to power-supply rails or other threshold voltages (Reference 1 and Figure 1). This resistor significantly reduces current-output capability and the output-voltage swing with low-resistance loads. The alternative approach is to use fuses or other current-limiting devices, which precede these clamps’ high energy-absorption capability

    Hybrid Supercapacitors Are — Well — Super

    Kurt.energy is promoting a new line of hybrid supercapacitors. By itself, that wouldn’t be very newsworthy, but the company claims these graphene-based supercapacitors merge the best features of both supercapacitors and lithium-ion batteries. Based on technology from a company called Shenzhen Toomen New Energy, the capacitors are optimized for either high energy or high power. They can reportedly charge and discharge 10-20 times faster than lithium-ion batteries. Of course, we’ve heard wild claims surrounding graphene capacitors before and, so far, they haven’t seemed very credible.

    Why Some Chips Have Inconvenient Pinouts

    If you’ve ever handled a chip with a really strange or highly inconvenient pinout and suspected that the reason had something to do with the inner workings, you may be interested to see [electronupdate]’s analysis of why the 4017 Decade Counter IC has such a weirdly nonintuitive pinout. It peeks into an IC design dating from the 1970s to see an example of the kind of design issues that can affect physical layout.
