摘要： Systems for displaying images. The system comprises a digital-to-analog converter, in which a first conversion stage selects first and second voltages of a plurality of reference voltages according to m most significant bits of a k bit input signal; and a second conversion stage converting n least significant bits of the k bit input signal to a voltage between the first and second voltages. In the second conversion stage, according to first and second bits of the least significant bits, a first switching capacitor unit charges a first capacitor during a first period and then the second switching capacitor unit performs a first charge sharing between the first capacitor and a second capacitor, and the first switching capacitor unit charges the first capacitor again and then the second switching capacitor unit performs a second charge sharing between the first capacitor and the second capacitor.

摘要： An electromagnetic digitizer having a sensor segment that includes a generally longitudinal network of conductive lines. Two or more conductive lines are coupled in parallel. To enhance sensitivity, the adjacent lines are interconnected along the longitudinal structure, using interconnections in the form of short lines, oriented at an angle. The sensor segments may be miniaturized, to facilitate integration into a display module using semiconductor fabrication processes. Various sensor array structures may be implemented using the sensor segment structures. The sensor array may include longitudinal sensor segments arranged in a parallel array. To further enhancing sensitivity of the sensor array, additional lines may be provided between adjacent longitudinal sensor segments. The sensor array may also include half loop (or U-shaped) sensor segments arranged in an overlapping parallel array, or full loop sensor segments arranged in an overlapping parallel array.
