    How to fix your simulations when the macromodel’s voltage noise doesn’t match the datasheet

    When responding to questions posted on TI E2E™ Community forums , we frequently run simulations using TINA-TI ™ software, a SPICE-based simulation program. Since we are always in the process of updating our simulation models, we sometimes run across SPICE models that are old, outdated or incorrect when modeling performance parameters. One recent example involves the voltage-noise density of the OPA2333...

    How does precision lead to automotive safety?

    Semiconductor content keeps increasing in automobiles, thanks to the number of sensing technologies. In a span of ten years, the number of sensors has increased steadily across all sensor types. This trend is likely to continue, as more features, which were previously only offered in luxury vehicles or available for purchase after-market, become crucial and in some cases mandated by governing bodies. Advanced driver...

    RF sampling: analog-to-digital converter linearity sets sensitivity

    In my previous post , I discussed details of third-order intermodulation (IM3) linearity parameters in active devices. Now let’s apply those techniques and parameters to a real RF-sampling receiver. The key active components in the lineup are the low-noise amplifier (LNA) and the analog-to-digital converter (ADC). The receiver antenna is “looking at the world” (that is, the entire frequency spectrum...

    Eliminating noise from the factory floor

    Industrial automation systems use microprocessors, digital signal processors (DSPs) and a network of sensors to control electromechanical processes. These components are highly sensitive, yet operate in environments filled with electrical noise caused by motor drives, electromagnetic interference (EMI) and a variety of other possible sources. Electrical noise is often transmitted via the central direct current (DC...

    The difference between hysteretic-mode converters and traditional regulators

    When designing a power circuit, many of the selections available on the market, such as traditional voltage and current-mode regulators, look similar. You know it will do a certain job - for example, step-down DC/DC conversion - but you may not know how the many choices compare to each other. If you haven’t considered it before today, my recommendation is a hysteretic-mode converter. Hysteretic-mode converters...

    Health monitoring devices get a jolt from MCUs

    The market for fitness products received a jolt several years ago when wristband-sized health monitors burst on the scene. Then, smartwatches made their appearance and they were able to gather more advanced health-related data. Now, telemedicine is steadily climbing in popularity. In fact, some say that telemedicine, which will rely on remote health monitoring devices to a great extent, holds tremendous promise for reducing...

    Laying out an inverting buck-boost converter for success

    It is common knowledge in the DC/DC converter domain that a buck converter or regulator integrated circuit (IC), such as the LM5017 family, can create a negative V OUT from a positive V IN . At first glance, the schematic of an inverting buck-boost converter using a buck regulator IC looks deceivingly similar to a buck converter (Figure 1a and 1c). But there are important differences in the two circuits, both in terms...

    How do automotive cabin sound-enhancement systems work?

    As drivers spend more and more time in their cars, manufacturers are working to make sure that the car cabin is as comfortable as possible. An increasing number of car buyers are looking at noise as one of the decisive factors when selecting a car. Most car cabin noises like road noise, wind noise and rattling interiors are all undesirable – they are intrusive, reduce the driver’s mental processing power...

    How to implement IEEE 1588 time stamping in an Ethernet transceiver

    This post is co-authored by Rob Rodrigues . The Institute of Electrical and Electronics Engineers (IEEE) 1588 Precision Time Protocol (PTP) offers a way to synchronize the time between different nodes on an Ethernet network. Typically, IEEE 1588 PTP clock-synchronization accuracy is significantly less than 10µs, making it suitable for applications ranging from factory automation to telecommunications. For instance...

    How to select the right retimer for HDMI 2.0 applications

    High-Definition Multimedia Interface (HDMI) is a popular video interface that uses transition minimized differential signaling (TMDS) as the main communication channel. Each TMDS data lane can support up to 6 Gbps for HDMI 2.0 channels, which is important in maintaining signal integrity over transmission media. This can be quite challenging since the high speed signal suffers loss automatically while transmitting in the...

    Quantifying harmonic distortion: Estimating THD without performing a full FFT operation

    Continued from Part 1 of my blog series on quantifying harmonic distortion. As a less computationally intensive alternative to calculating each harmonic RMS value for THD, you can estimate THD by calculating the total RMS of the harmonics (excluding the fundamental). First, calculate the RMS of the fundamental and subtract it from the total RMS. Equations 1 through 4 are the resulting THD representations: ...
