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…
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…

Design engineers working on low-electromagnetic interference (EMI) applications typically face two major challenges: the need to reduce the EMI of their designs while also shrinking solution size. Front-end passive filtering to mitigate conducted EMI generated by the switching power supply ensures compliance with conducted EMI standards, but this method can be at odds…
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…

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…
Throughout every automobile lies an extensive in-vehicle network of sensors, motors and switches. As these networks grow to accommodate increasing connectivity across the vehicle, their overall power consumption grows as well, which can negatively impact vehicle emissions.
There are several approaches available to reduce power consumption, depending on the network protocol in use. For classical Controller Area Network…
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…
