Design a circuit for ultra-low power sensor applications
Sensors monitoring mechanical and biological systems must often scavenge power from the thing being sensed. The oscillator circuits shown here let you operate those sensors. Sensor circuits that connect to thermocouples, electromagnetic mechanical-to-electrical transducers, and piezoelectric mechanical-to-electrical transducers often use oscillators powered through energy harvesting from solar cells and other sources. These power sources can […]

What are the advantages of a three op-amp instrumentation amplifier?
An instrumentation amplifier (INA) built using three operational amplifiers (op amps) can provide performance advantages in terms of high input impedance, low output impedance, easily adjustable gain, excellent common-mode rejection ratio (CMRR), high accuracy, and high open-loop gain. This article examines the basic design of INAs and their performance benefits, then discusses some application considerations, […]
Achieving isolation in an isolation amplifier
Isolation amplifiers create a galvanic isolation barrier between input and output circuits to protect sensitive equipment and personnel from high voltages. Such isolation can be optical, capacitive, or inductive in an isolation amplifier. This FAQ will help us understand how each isolation type works and how they differ. How do optical isolation amplifiers work? Optical […]
