Race-track fluxgate with adjustable feedthrough
نویسنده
چکیده
Improved shape of the race-track fluxgate sensor is suggested, which allows precise symetrization of the sensor and thus lower level of the feedthrough signal. The sensor has high untuned sensitivity (16.7 V/T per 1 turn) and low crossfield response thanks to the high shape anisotropy. The closed core and low cross-section guarantee low power consumption, low noise and stable offset. The sensor can be made resistant to vibrations and mechanical and temperature shocks. The sensitivity obtained after the proper tuning was 1.1 V/μT.

Tuning Current-output Fluxgate
The current-output fluxgate may be tuned by using a serial capacitor. Such tuning increases the sensor sensitivity in the situation when the pick-up coil has low number of turns. We achieved a signal/feedthrough ratio improvement by a factor of 5. The measured parameters fit the simplified theoretical model within 20% deviation

متن کاملFeedthrough reduction technique for track-and-hold circuit with body-bias control circuit
This paper describes a feedthrough reduction technique for a track-and-hold (T/H) circuit with a body-bias control circuit. We propose a T/H circuit with a feedthrough canceller. This circuit cancels a leaking signal to the output node through the parasitic capacitance by using an opposite-phase signal. The simulation results using 90-nm CMOS technology demonstrate a feedthrough of −89.4 dB and...
متن کاملWide-range single-ended CMOS track-and-hold circuit
This paper investigates the performance of a MOS trackand-hold circuit as the front end of a wide input range and highspeed single-sided ADC. In order to reduce charge injection and clock feedthrough errors, a new technique for employing a dummy transistor in the bootstrapped switch of the track and hold circuit is introduced. Performance of the proposed circuit for the two cases of constant an...
