Abstract: An example embodiment includes a liquid crystal on silicon (LCOS) system. The LCOS system includes multiple pixels, a pixel voltage supply source (voltage source), an external buffer, and a local buffer. The voltage source is configured to supply an analog ramp to the pixels. The external buffer is configured to buffer the voltage source from the pixels. The local buffer is configured to buffer the external buffer from a subset of pixels of the plurality of pixels.

Abstract: An example embodiment includes a continuity testing method of a pixel in a liquid crystal on silicon integrated circuit. The method includes writing a first voltage to a pixel. The pixel is isolated and a wire that is selectively coupled to the pixel is discharged. The method also includes enabling a sensing amplifier configured to sense voltage on the wire. The pixel is electrically coupled to the wire and a resultant voltage on the wire is sensed.
