  • Patent number: 11978506
    Abstract: This document describes a spatial light modulator that comprises a pixel array having a plurality of pixels whereby each pixel in this array is communicatively coupled to a digital pixel circuit which are in turn all coupled to a bit-plane control circuit. The bit-plane control circuit is configured to generate, using a Pulse Code Modulation (PCM) algorithm, bit-plane signals that are used to control the sample and hold functions performed by each of the digital pixel circuits so that the pixel array may carry out its scanning function accurately and in a power efficient manner.

  • Patent number: 10819366
    Abstract: Various embodiments may provide a delta sigma modulator for generating a digital output voltage. The delta sigma modulator may include a capacitance-to-voltage converter for converting a sensed continuous-in-time applied capacitance signal to a delta analog output voltage signal. The modulator may also include an integrator circuit arrangement configured to generate an analog output voltage signal based on the delta analog output voltage signal. The modulator may additionally include a quantizer circuit arrangement configured to generate the digital output signal based on the analog output voltage signal. The modulator may further include a voltage digital-to-analog converter configured to generate the analog charging voltage based on the digital output signal, thereby generating the delta analog output voltage signal based on the digital output signal.
