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.
