Matter, formerly known as Project Connected Home over IP (CHIP), is a royalty-free connectivity standard developed within the Connectivity Standards Alliance, formerly the Zigbee Alliance. Matter runs on Thread and Wi-Fi® network layers and uses&...
If you design automotive systems, you may feel tremendous pressure to redefine vehicle powertrain systems to meet the reduced greenhouse gas (GHG) emissions goals established by initiatives in the European Union, United States, China and Japan, just to name a few. To meet these targets, some automobile manufacturers are implementing 48-V systems for mild hybrid electric vehicles…
For athletes to perform at their highest level – to run a mile in less than five minutes or leap into the air and dunk a basketball – they need strong muscles. The heart supplies blood through the veins to the muscles to enable movements such as gripping an object with your hand or moving a finger when your brain instructs it to. But without muscles, these spectacular…
Smart speakers have become ubiquitous in homes, raising the bar for consumer audio quality standards in household items. New audio features are popping up in unlikely places: digital voice assistants in coffeemakers that announce a fresh brew, or digital thermostats that can tell you the weather while playing your favorite jazz album (Figure 1). As consumer reliance on smart home…
When you can create automotive applications that do more with fewer parts, you’ll reduce both weight and cost and improve reliability. That’s the idea behind integrating electric vehicle (EV) and hybrid electric vehicle (HEV) designs.
What is powertrain integration?
Powertrain integration combines end equipment such as the onboard charger (OBC), high-voltage DC/DC (HV DCDC), inverter and power distribution…
For years, passive infrared sensors and lasers have sensed remote objects or measured range in applications such as robotics, level sensing, people counting, automated doors and gates, and traffic monitoring. But with demand for higher precision and resiliency against environmental influences such as bad light, harsh weather conditions and extreme temperatures…
Electronic systems in industrial, automotive and personal computing applications are becoming increasingly dense and interconnected. To improve the form factor and functionality of these systems, diverse circuits are packed in close proximity. Under such constraints, reducing the effects of electromagnetic interference (EMI) becomes a critical system design…

In 1976, National Semiconductor (now TI) introduced the LM2904, one of the most popular operational amplifiers (op amps) worldwide. It was a time when 8-track tapes played your favorite tunes in the car, a vehicle could get you an average of 14.22 miles to the gallon, and people used…
Radiation-hardened low-dropout regulators (LDOs) are vital power components of many space-grade subsystems, including field-programmable gate arrays (FPGAs), data converters and analog circuitry. LDOs help ensure a stable, low-noise and low-ripple supply of power for components whose performance depends on a clean input.
But with so many LDOs available on the market, how do…

The technical article, “What is a smart DAC?” explained what a smart digital-to-analog converter (DAC) is and how it can bring value to many applications. Smart DACs can improve design efficiencies by reducing the burden of software development, and they provide many useful functions that would…
Engineers are always striving to make things more effective, more efficient and less expensive. System designers typically use a precision digital-to-analog converter (DAC) when they need very precise control of an analog output. A design that requires precise control of auxiliary functions typically also needs a combination of discrete analog components…
In part 1 of this series, I covered issues related to power consumption in single-supply operational amplifier (op-amp) circuits with a sinusoidal output and DC offset. I also discussed two techniques for reducing power consumption in these circuits: increasing resistor sizes and picking an op amp with a lower quiescent current. Both tactics are available in most…
The 12-V lead-acid battery is a staple in automotive electronic systems such as automotive cockpits, clusters, head units and infotainment. Monitoring the battery voltage is necessary in order to maintain and support the power requirements of the modern vehicle. Although automotive batteries can withstand wide voltage transients that exceed their nominal voltage…
Advancements in ultrasound imaging technology, along with rising demand for minimally invasive diagnostics and therapeutics, have made it possible to implement ultrasound applications for medical use. For example, employing ultrasound for remote patient monitoring has become increasingly popular given its cost-effective, safe and fast diagnostic…
This is a guest technical article from Cadence® Design Systems.
So, you have designed a circuit and are ready to start your simulation. How do you begin?
To start, you need to define a simulation profile. Simulation profiles define the various aspects of a simulation or analysis for various simulators, including PSpice® for TI. Definitions may include the analysis you want to perform and the resources you want to…
Many automotive, communication and industrial systems take real-world input and provide corresponding outputs to create a precise control response. For example, autonomous driving detects and controls vehicles based on the real-world input of their proximity to other objects. In telecommunication radios or base stations, the outdoor temperature can affect power requirements for transmission…
