May 2019 N2 - Ultrasound energy transfer systems can be an alternative for sensor-chargers aiming battery replacement avoidance and can be used in machine tool applications. An ultrasound input source can be used to send an acoustic signal through a machine. The signal is received by an ultrasound receiver based on piezoelectric component and should be converted into an electrical signal to supply or charge the sensor. Notwithstanding, for rotating machines, an air gap must be considered between the input source and the machine tool part. This paper deals with the acoustic-electrical energy transfer considering the changes in the propagation media of the ultrasound. Theoretical results are verified by means of an experimental setup.

In this paper, a linear-assisted zeta converter is presented. The linear regulator circuit is composed by three bipolar transistors and an operational amplifier, which drives the transistor based on the error between the output voltage and its reference. The modeling of the whole circuit is presented, as well as a design example. The modeling of the zeta converter is similar to the conventional topology modeling, except the fact that the linear regulator current is considered as an extra state that substitutes the state regarding the output capacitor voltage. The zeta converter can be designed independently of the linear regulator circuit and simulations are used to validate the static operation of the overall topology. Experimental results confirm in practice the ripple compensation of the main zeta converter, where extra current is provided by the main converter, in order to drive the linear regulator that is responsible for the ripple compensation.

In this sense, an analysis and design methodology of resonant rectifiers is proposed, in which, iterative numerical solutions are replaced by analytic solutions with the help of computer algebra systems. The method allows obtaining the AC-to-DC transfer function, the quality factor, the phase angle and the resonance frequency. A case study for the Class-E zero-derivative voltage switched resonant rectifier is performed. Experimental results are shown in order to validate the theoretical approach.

The quantiser allows a dynamical adjustment of the step size dependent on the input signal waveform. This mitigates the limited slew rate of delta encoded ADCs. Energy consumption induced by 1 LSB ripple is removed by the quantiser. The segmented current-steering DAC allows simple control, good monotonicity and improved transient response when compared to previous design as well as potential power reduction.

The circuit is based on 3-stacked CMOS using gate control circuits to drive maximum current which indicates minimized on-resistance of the HV-driver thus achieving faster switching. The circuit is designed and fabricated using 65 nm CMOS TSMC process technology with a nominal voltage of 2.5 V and with a supply voltage of 5.5 V. Since the design is based on stacked CMOS transistors, the circuit is technology-independent. The initial on-resistances of the driver pull-up and the pull-down paths have an improvement of 75% and 36% respectively. Due to a buck converter switched by the designed HV-driver, output voltages in the range of 0.45 V to 2.45 V can be achieved from different high supply voltages in the range of 3.5 V to 5.5 V.

The thermometer coded register is controlled by sequentially stepping one or two steps up or down dependent on the control input. The enhanced step size mitigates the slew-rate limitation if the DAC is used in a delta-encoded tracking ADC. The sequential switching of thermometer coded DAC register does not require a binary to thermometer decoder and reduces complexity of error compensation.

Piezoelectricity is an interesting key to perform the interface between environmental extracted energy and the power delivered to the load due to the use of mechanical vibration and resonance features. However, it is necessary for a detailed analysis in order to obtain an accurate understanding of the system. In this regard, some works deal with the normalization procedures to analyze the piezoelectric component behavior based on the mechanical resonance frequency. In order to enhance the system modeling, the electromechanical resonance frequency must also be analyzed. This paper deals with an approach to model the piezoelectric component that allows analyzing several unitless parameters that are critical to improve the performance of the system. In addition, a state-space model for the piezo-harvester based on the Class-E resonant rectifier is presented. Some experimental results are shown to validate the theoretical approach. [2019-0082].

This article outlines a technique making it possible to employ analog computers to the solution of such equations. Using iterative techniques it is even possible to setup a hybrid computer, i. e. a combination of a classic digital and an analog computer, where the analog portion can be used as a co-processor. If the solutions obtained by pure analog computing are not of the required accuracy, it is possible to use these as initial vectors for a classic iterative algorithm running on the digital computer to further enhance the precision of the solution obtained.

T1 - Signal processing for magnetic micro torque sensors T2 - Sensors and Actuators A: Physical N2 - A novel type of signal processing for a magnetic micro torque sensor is described and simulated. The sensor principles are based on a soft magnetic core shaped as a yoke, two current-carrying coils, a soft magnetic amorphous ribbon with strong magnetostrictive properties that is fixed on a shaft, and at least two magnetic flux-density sensors. The sensor determines directly the change of permeability of the amorphous ribbon on the shaft. Nevertheless, the variation of the air gap between the sensor and the rotating shaft affects the measurement principle. Therefore, the magnetic flux density is measured at two positions, one at the face of the soft magnetic core and the other beside the face of the core in the area of the stray flux. The evaluation of these two flux densities yields the distance between the sensor and the shaft as well as the permeability of the amorphous ribbon. The problem arising with this practice is the determination of the sensitivity of the flux-density sensors. As the current-carrying coils are alternately operated in a common and a push-pull mode, the unknown sensitivities of the flux-density sensors do not affect the evaluation of the permeability of the amorphous ribbon on the shaft.

CDS has the disadvantage that input signals of high frequencies are folded back to the base band caused by sampling the continuous input signal. However, the circuit presented here uses a new method to limit the bandwidth of the CDS input signal. Two filter-capacitors, one for each clock phase, are periodically connected to the input of the CDS circuit. As the input signal is low-pass filtered by the ohmic output resistance of the optical sensor in conjuction with the filter-capacitors, aliasing can be avoided. Measurements of a test circuit demonstrate the effectiveness of this principle.
