A system and method for implementing a dynamic menu characterized by a real-time menu architecture. To facilitate the passage of light to the photodiode, each pixel includes a via wave guide defined in the metallization layer formed over the pixel’s photodiode. The modified state machine providing fast authentication remains compatible with the classic state machine implementing the wireless fidelity standard. The single-ended amplifier functions such that it is only operable during an CCD signal input; otherwise, the single-ended amplifier is bypassed such that a video signal is only sampled by the differential amplifier.
