The first installment of this series introduced the boundary plot, an often-misunderstood plot found in instrumentation amplifier (IA) datasheets. It also discussed various IA topologies: traditional ...

Keeping track of extremely low current levels is often essential when developing or testing low-power devices, especially in the field of embedded systems and battery-operated electronics. For battery ...

In today’s information-driven society, there’s an ever-increasing preference to measure phenomena such as temperature, pressure, light, force, voltage and current. These measurements can be used in a ...

Analog electronics are electronic systems that use continuous signals to represent and process information. This is in contrast to digital electronics, which use discrete signals to represent and ...

Abstract: This article introduces a high-acoustic-dynamic-range and low-power digital microphone based on the electrostatic force feedback control (EFFC). The proposed design adjusts the sensitivity ...

During the last 3 decades, PET has become a standard-of-care imaging technique used in the management of cancer and in the characterization of neurologic disorders and cardiovascular disease. It has ...

Neuroscience research into how complex brain functions are implemented at an extra-cellular level requires in vivo neural recording interfaces, including microelectrodes and read-out circuitry, with ...

The Boise State University NMR facility instrumentation was funded through an NSF CRIF-MU/RUI (Grant number 0639251), as well as funding from the State of Idaho and funding from the Department of ...

The lock-in amplifier allows tiny signals from sensors to be captured with precision despite unavoidable noise limitations and other signal-chain test and measurement challenges. There are some basic ...

An “ideal” or perfect operational amplifier is a device with certain special characteristics such as infinite open-loop gain, infinite input resistance, zero output resistance, infinite bandwidth, and ...
