Flip-flop with internal circuit for generating inflated low and high pulse width signals

Abstract

Example flip-flops comprise a circuit that receives a primary clock signal, generates a clock buffer signal having a series of pulses, each delayed by a set amount of time relative to a corresponding pulse of the primary clock signal, generates an intermediate clock signal based on the primary clock signal and the clock buffer signal, generates inflated low pulse width clock signals, each having a low pulse width that is greater than a low pulse width of the primary clock signal. Latch stages within example flip-flops include one or more components that are controlled by the inflated low pulse width clock signals. Example flip-flops include high-speed flip-flops and standard flip-flops. Larger circuits, such as a clock divider circuits, may incorporate multiple example high-speed flip-flops to improve performance.
