Shielded Fluxgates for Open-Loop Current Transducers; Measuring High Flux Densities Fast
As the basic components to build a fluxgate are just a piece of soft magnetic material with some turns around, fluxgates can even be integrated onto silicon chips , for example for the use as a small compass in watches.
Two-axis micro fluxgate sensor on single chip
Actual chip size was 3.1·3.1 mm2 . The sine and cosine signals of two-axis fluxgate sensor had a good function of azimuth compass .
A high accuracy magnetic heading system composed of fluxgate magnetometers and a microcomputer
ABSTRACT This paper presents a magnetic heading system consisted of two fluxgate magnetometers and a single- chip microcomputer. The system, when compared to gyro compasses , is smaller in size, lighter in weight, simpler in construction …
Progress in CMOS integrated measurement systems
Figure 1shows a micrograph of an integrated CMOS compass system based on planar microfluxgate scnsors [3]. The prototype magnctic systcm contains, on a single chip , two orthogonal microfluxgate sensors and the clectronics for fluxgate excitation and signal read-out.
CMOS planar 2D micro-fluxgate sensor
The chip has a power consumption of 12.5 mW for a 17 mA-peak driving current … Keywords: Integrated compass ; Planar fluxgate ; Amorphous core .
Microfabricated fluxgate sensors with low noise and wide bandwidth
Planar micro-fabricated fluxgate sensors were first pro- posed by Seitz in 1990,who demonstrateda semi-integrateddevice … Since then, several groups have produced integrated devices on a chip for compasses and other relatively low bandwidth applica- tions e.g. [3 - 51.
Progress in CMOS integrated measurement systems
Fig. 1 shows a micrograph of an integrated CMOS compass system based on planar microfluxgate sensors [3]. The prototype magnetic system contains, on a single chip , two orthogonal microfluxgate sensors and the elec- tronics for fluxgate excitation and signal read-out.
Folding Viterbi detector with reduced complexity for EPRML system applications
Planar micro-fabricated fluxgate sensors were first pro- posed by Seitz in 1990,who demonstrateda semi-integrateddevice … Since then, several groups have produced integrated devices on a chip for compasses and other relatively low bandwidth applica- tions e.g. [3 - 51.
Smart sensor system application: an integrated compass
A number of magnetic sensor systems for navigational use have been described until now [Pet86, Spr93, Ho194, Ma195, Got951, but none of them have been shown to function as a complete compass system on a single chip or multi chip module. With the introduction of micro-machined fluxgate sensing elements with electroplated permalloy cores [Kaw95] this problem has …
A CMOS front-end circuit for integrated fluxgate magnetic sensors
solution proposed will be useful not only for a System on compass devices have been proposed in … Chip solution (SoC), but also for a System on Package topologies of planar integrated micro- fluxgate [1-2] have .
