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…

Millimeter-wave (mmWave) radar is one of the primary sensing modalities for automotive and industrial applications because of its ability to detect objects from few centimeters to several hundred meters with high distance, angle and velocity accuracy, even in challenging environmental conditions.
A typical radar sensor consists…
Manufacturers build mild hybrid electric vehicles (MHEVs) with the ultimate goal of reducing greenhouse gas (GHG) emissions. An MHEV incorporates a 48-V motor-drive system connected to the transmission system of a vehicle. To reduce GHG emissions, the internal combustion engine (ICE) in an MHEV turns off when the vehicle is coasting, while the 48-V motor system charges the 48-V…
Differential signaling is becoming more popular in analog front ends, especially in factory automation designs, to interface with differential analog-to-digital converters (ADCs). In this article, I’ll discuss the advantages of a fully differential signal path, explain why precision is important and discuss how new fully differential amplifiers can meet precision challenges.

In recent years, the popularity of battery-powered electronics has made power consumption an increasing priority for analog circuit designers. With this in mind, this article is the first in a series that will cover the ins and outs of designing systems with low-power operational amplifiers (op amps).
In the first installment, I will discuss power…
Faced with shrinking space constraints and increased robustness requirements, industrial and automotive power-supply designers must carefully choose the best power design topologies to meet their application needs. Isolated choices include modules as well as discrete and integrated solutions; each has its own trade-offs. Modules are encapsulated solutions with common input/output…
The world population is 7.8 billion and is on the rise, with an estimate of 10 billion by 2050. The growing population needs basic necessities such as food, clothing and ever-increasing comforts safely and securely. Industry 4.0 technologies today and upcoming Industry 5.0 innovations in smart manufacturing, smart buildings and smart grid can serve these…
When designing for increased efficiency in heating, ventilation and air-conditioning (HVAC) systems, sensor accuracy and consistency have a significant effect. A system’s ability to accurately sense and measure temperature and humidity levels of inside and outside air sensors, damper controls, thermostats and fans minimizes system run time because the system can use more data…
Because satellites on space missions are inaccessible once launched, acquiring accurate telemetry data to monitor the state of health of the satellite sub-systems can help set a baseline to indicate a working system, while fluctuations can indicate...
Bluetooth® Low Energy is on a path to become ubiquitous. The Bluetooth Special Interest Group estimates that by 2024, all new phones, tablets and laptops will support Bluetooth Classic and Bluetooth Low Energy. They also expect 35% of devices to ship with single-mode Bluetooth Low Energy by 2024, which represents 300% growth in annual shipments.
The reason for this is the versatility of Bluetooth Low Energy. Bluetooth…
