comprised of loudspeakers placed in convenient locations around a broadcasting area, an amplifier to increase the sound, and a mixer that adjusts audio levels. The user speaks into a microphone, and the sound is transmitted through connected cables, or a wireless system, out through the speakers. Some systems also include microphones or intercoms near the speaker locations, allowing the listener to reply to the central location. These responses are not broadcast to the entire system, however, but only to...

The optimal M1,2 width (W) is determined for several M1,2 lengths (L) and bias current Ibias, and the overall optimal set of values is W=600µm, L=3µm, Ibias=53µA. Noise measurements show that 1/f noise has a slightly higher impact than does white noise, when both contributions are A-weighted. The expected SNR degradation introduced...
