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.

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.

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.
