The human ear is very good at detecting noise or missing cycles in a waveform, and since we have two ears, we can monitor two signals at once. I recently repaired an older lab instrument containing a quadrature encoder made with an incandescent ...

When you design for electronics applications, such as sensor or amplifier bias supplies or special waveform generators, a controlled constant-current source or sink circuit can serve as a useful building block. These circuits exhibit high ...

You sometimes need to measure a small signal in the presence of a large common-mode signal. Traditional instrumentation amplifiers that use two or three op amps in their internal structure find common use in these applications. The circuit in ...

Part 1 Preserved DC Precision In a typical operational amplifier circuit, a portion of the output is fed back to the inverting input (Figure 9). Errors that are present on the output which were generated in the loop are multiplied by the feedback ...

by Jino Loquinario, Analog Devices Analog Dialogue Introduction It is normal, and almost expected, to be faced with applications for which a solution does not appear to exist. To meet their requirements would require us to think of a solution that ...

Rusty Juszkiewicz, Analog Devices Analog Dialogue Question: Can we generate a differential output signal using instrumentation amplifiers? Answer: As the drive for precision moves forward, fully differential signal chain components are desired for ...

Uttam Sahu, Texas Instruments Many imaging products are moving toward more efficient LED array-based solutions and away from traditional technologies such as lasers or lamps. Applying resistive voltage dividers enables the linear forward biasing of ...

Lou Frenzel Electronic Design Often used for overcurrent protection, current-sense amplifiers are now finding homes in a wide array of applications, including automotive electronic fuses and three-phase motor control. If you're seeking a way to ...

D Ramírez, S Casans, C Reig, AE Navarro, and J Sánchez EDN Although well-known to active-filter theorists and designers, GICs (generalized impedance converters) may be less familiar to analog generalists. Comprising a one-port active ...

Sponsored by: Texas Instruments. Generally speaking, an op amp doesn’t make for a good comparator. To achieve optimal performance and avoid additional debugging, an IC comparator is the best bet. A comparator is a great circuit because it ...
