Analog Dialogue Question: I have heard that it is possible for a gyroscope heading to accumulate drift error over time. Can this happen in my IMU? Answer: A MEMS gyroscope, which measures angular rate, has several internal contributors to error, ...

By Tom Lecklider Evaluation Engineering Most electronic engineers know that a transistor's base-emitter voltage (V BE ) has a temperature coefficient (TC) of about 2 mV/ C. However, for precision temperature sensors, about isn't good ...

There was a time when it wasn't so rare to discover an unusual, scope-like object in an electronics lab. This was the curve tracer, able to display detailed characteristic curves of many components. Early models displayed vacuum tube curves; ...

High frequency Helmholtz coils are often used to generate uniform but time varying high frequency magnetic fields for a number of applications such as magnetic field susceptibility, calibration, and scientific experiment. A high frequency Helmholtz ...

Analog Dialogue Instrumentation amplifiers (in-amps) can condition the electrical signals generated by sensors, allowing them to be digitized, stored, or used to control processes. The signal is typically small, so the amplifier may need to be ...

The other day Linda from Purchasing came to me with a problem: Lou from Operations needed to source a replacement for a shorted diode on a switching power supply. The darned thing was marked with a strange part number that no amount of Googling ...

The LTC2983 solves the unique problems presented by all standard temperature sensors to produce unmatched conformity and ease-of-use. Temperature measurement is not new. Galileo invented a rudimentary thermometer capable of detecting temperature ...

Ken Wada embedded.com Temperature is one of the most common parameters monitored by an embedded system. There is a wide array of temperature sensors available to achieve this. The sensor types can range from exotic black body detectors to the ...

Design Note 533 Introduction Linear Technology’s Over-The-Top® op amps have an input stage topology that allows them to operate closed loop well above the positive supply rail. The inputs remain high impedance when split apart in voltage ...

Electronics Engineering Herald When National Instruments developed its virtual instrumentation product, it created a new market and helped many design engineers to explore personal computer as a test and measurement platform. The availability of ...
