Abstract
Provided herein are apparatus and methods for single phase spot circuits. In certain implementations, a single phase spot circuit propagates a spot from input to output in response to a clock edge of a single phase clock signal. The single phase spot circuit holds the spot for about one clock cycle, thereby providing higher maximum operating frequency relative to multiphase spot circuits that hold a spot for about half of a clock cycle. Two or more single phase spot circuits can be electrically connected in a ring to operate as a spot divider. The single phase spot circuits can be used to advance a spot, represented using either a one or a zero, from one spot circuit to the next in response to a clock edge. In certain implementations, as the spot advances, a single phase spot circuit clears the spot from its input via a feedback element.
