Clocking nanocircuits for nanocomputers and other nanoelectronic systems

Prospective performance bounds are determined by simulation for a class of all-nanoelectronic clocking circuits. Such nano circuits could be utilized as on-chip master clocks for stand-alone nanosystems, as local clocks within nanoelectronic computers, or as local oscillators in mixed-signal nanoelectronic applications. Designs and simulation results are presented for these nano circuits, which are intended to be manufacturable using presently available nanodevices and nanofabrication techniques. The results presented here indicate that such clocking nano circuits, if built using presently available devices, could achieve operating frequencies up to approximately 1 GHz for analog applications and ISO MHz for digital nanoelectronic systems.
