The dual approach of digital and analog lock-in amplifier technologies has continued to advance the precise extraction of weak signals from noise-laden environments. These devices are indispensable in ...

Semiconductor Engineering sat down to discuss what’s changing in analog design with the shift toward heterogeneous integration and more safety- and mission-critical applications with Mo Faisal, ...

A rapid increase in wireless connectivity and more sensors, coupled with a shift away from monolithic SoCs toward heterogeneous integration, is driving up the amount of analog/RF content in systems ...

What is an analog front-end (AFE)? Why use an AFE? AFE tradeoffs in energy-meter design. Sensors provide analog signals that need to be converted to digital values via analog-to-digital converters ...

In this DI, high school student Tommy Liu modifies a popular low-cost DIY oscilloscope to enhance its input noise rejection and ADC noise with anti-aliasing filtering and IIR filtering. Three ...

In a digital world, why bother with analog? Well, sometimes it can still be the right solution. Take, for instance, the analog multiplier (see figure). At its simplest, it’s a circuit that leverages ...

CAMBRIDGE, U.K. – A small Microsoft Research team had lofty goals when it set out four years ago to create an analog optical computer that would use light as a medium for solving complex problems.
