It is based on chain of delay elements composing a regular scalable structure. The scheme is analogous to the sound direction sensitivity nerve system found in barn owl. The circuit occupies small silicon area, and its direct mapping from time to position-code makes conversion rates up to 500Msps possible. Specialty of the circuit is the structural and functional symmetry. Therefore the role of start and stop signals are interchangeable. In other words negative delay is acceptable: the circuit has no dead time problems. These are benefits of the biology model of the auditory scene representation in the bird's brain. The prototype chip is implemented in 0.35μm CMOS having less than 30ps single-shot resolution in the measurements. |
