Application No. 09/435,864
insufficient triggering of the rising and falling edges of an
output signal. The instant invention, rather than relying on a
first clock for triggering both the rising and falling edge of
the output, utilizes a second clock in the first stage for
triggering the falling edge of the output. This second clock
also controls the second stage output.
Representative independent claim 1 is reproduced as follows:
1. A method for dealing with an unspecific underlap
requirement in timing-sensitive dynamic circuits of a multi-
clocked system comprising:
receiving a first clock signal in a first stage;
controlling an output from the first stage using the first
clock signal; and
receiving a second clock signal in the first stage;
controlling the output from the first stage using the second
clock signal.
