    Why Have an Air Gap?
    https://www.powerelectronics.com/content/why-have-air-gap?PK=UM_Classics04119&utm_rid=CPG05000002750211&utm_campaign=24648&utm_medium=email&elq2=bae2aeab5e6c4da0a72f41f46fbaf2a0

    What exactly is the function of the air gap? When asked this question, most engineers respond, “It prevents core saturation.” Although this may be true in certain cases, it’s not true in general. In fact, in a transformer, the air gap will not prevent saturation caused by excessive ac voltage polarization, as we will see. Further, the air gap has several other critical functions.

    What’s All This T-Coil Stuff, Anyhow?
    https://www.electronicdesign.com/analog/what-s-all-t-coil-stuff-anyhow?NL=ED-003&Issue=ED-003_20190405_ED-003_360&sfvc4enews=42&cl=article_1_b&utm_rid=CPG05000002750211&utm_campaign=24657&utm_medium=email&elq2=66d3a6b3b204415e82e2cbd2cb7522c0

    Adding a T-coil inductor and capacitor combo to your amplifier will extend its bandwidth. These circuits are also useful in high-speed digital I/O and video distribution.

    A T-coil uses a coupled inductor, essentially a transformer with three leads. It can double amplifier bandwidth, and the bridging capacitor gives it a constant input impedance.

    Millimeter-Wave Sensors Enhance Factory Safety
    https://www.electronicdesign.com/industrial-automation/millimeter-wave-sensors-enhance-factory-safety?NL=ED-005&Issue=ED-005_20190410_ED-005_195&sfvc4enews=42&cl=article_1_b&utm_rid=CPG05000002750211&utm_campaign=24756&utm_medium=email&elq2=c527d63e77f04ac99cffb11b96b63920

    When you think of a sensor, you probably don’t think of millimeter-wave (mmWave) radar. Now, though, you can add mmWave radar chips to your mental archive along with the other more traditional sensors. If you’re designing new systems requiring proximity detection and the presence and movement of people, these radar ICs just may be a solution to consider.

    Ultrasound: Don’t Be Blinded by Your Amplifier’s Slow Overload Recovery
    https://www.electronicdesign.com/analog/ultrasound-don-t-be-blinded-your-amplifier-s-slow-overload-recovery?NL=ED-003&Issue=ED-003_20190411_ED-003_764&sfvc4enews=42&cl=article_2_b&utm_rid=CPG05000002750211&utm_campaign=24814&utm_medium=email&elq2=57bcb54a94954afca6443ca00551369c

    Developing an ultrasound receiver with good overload recovery characteristics can greatly simplify HW/SW design and debug challenges, speeding up time-to-market and considerably enhancing image quality.

    Ultrasound receivers are frequently exposed to overload conditions during B-mode and pulsed Doppler operation. These conditions can saturate the amplifiers and/or the analog-to-digital converter (ADC) within the receive amplifier-front-end (AFE) signal chain. An ultrasound receiver with poor overload recovery characteristics can greatly complicate design, significantly reduce image quality, and lengthen time-to-market. This article reviews ultrasound system design challenges with regard to overload recovery, and presents a new approach to address this issue.

    Low Power Meets Variability At 7/5nm

    Reductions in voltage, margin and increases in physical effects are making timing closure and signoff much more difficult.

    Single-sideband demodulator covers the HF band
    https://www.edn.com/design/analog/4358621/Single-sideband-demodulator-covers-the-HF-band?utm_content=buffer73e69&utm_medium=social&utm_source=facebook.com&utm_campaign=buffer

    The modulator employs a phasing network to split a low-frequency audio signal into in-phase and quadrature (orthogonal) components. This circuit delivers a phase error of only 0.15° and has a low sensitivity to component tolerances, which are advantages over other phasing circuits (Reference 1). By reversing the direction of the network, that is, feeding the output with two orthogonal signals and tapping the input, the network functions as a detector.
