Abstract:
1. A hardware-programmable clock generator for an integrated circuit chip, comprising: a clock input portion; first and second clock outputs; a first feedback path coupling the first clock output to the clock input portion; a second feedback path coupling the second clock output to the clock input portion; and a first plurality of switches coupled to the first feedback path, each of the first plurality of switches configurable during manufacturing to couple a corresponding one of a first plurality of delay elements in series along the first feedback path, wherein the coupling of delay elements along the first feedback path controls the amount of time that clock edges associated with the first and second clock outputs are non-overlapping, and a first logic gate that generates the first clock output and a second logic gate that generates the second clock output, wherein each of the first and second logic gates comprises a NOR gate.
