You can effectively double the sample rate of a DAC by interleaving two DACs into a single unit. Updating each DAC on an alternating basis and switching to the appropriate output double the effective throughput of the overall system. It is ...

At times, designers face a limited amount of wire and/or a limited cost to communicate with a remote device such as a sensor. Many devices allow communication over an ac or dc power line employing an AM or FM modulation scheme. However, they tend ...

This article will describe how Bode plots can be used as a tool to quickly assess if your power supply design will meet the requirements for dynamic control behavior. Power supplies normally maintain a fixed output voltage via a control loop. This ...

The pressure-sensor amplifier circuit of Figure 1 offers a number of advantages over the traditional approach using the classic three-op-amp instrumentation amplifier. The circuit can operate from a single supply and uses only two op amps and 1% ...

When you are working with battery depending low power-consuming circuits, then you may need this innovative power switch. The concept is to save energy while the device is not operating but the battery is connected. Why we need to save energy We ...

Although the heyday of AM radio has passed, it remains an integral part of many lives as a means of communication in third-world countries, or simply tuning in for local news and weather. Amplitude modulation (AM) is by far the oldest form of ...

In test-and-measurement applications, you must provide overvoltage protection for the output terminals of amplifiers, power supplies, and similar components. The conventional way to accomplish this task is to add series resistors with the output ...

Readers will recognize the famous name Claude Elwood Shannon, widely renowned as the “father of information theory” and originator of many discoveries and inventions. Among these is an elegant and pioneering (First published in 1948!) ...

It may be hard to believe, but 2022 marks flash memory's 35th anniversary. Time, it appears, flies particularly quickly when a technology becomes as essential and widely adopted as flash storage (Fig. 1). Figure 1. Flash memory growth in all ...

Introduction Current-sense resistors, which come in a variety of shapes and sizes, are used to measure current in many automotive, power control, and industrial systems. When using very low value resistors (a few milliohms or less), the resistance ...
