Abstract:
1. A method, in a pulse width limiter output characterization device, for determining a maximum pulse width of a pulse width limiter, comprising: receiving an input signal; limiting a pulse width of the received input signal to generate a first intermediate signal; delaying the first intermediate signal by a known amount to generate a set signal; asserting a clock output signal in response to assertion of the set signal; and de-asserting the clock output signal in response to a receipt of a reset signal, wherein the asserted clock output signal is representative of the maximum pulse width of the pulse width limiter, wherein the pulse width limiter output characterization device has a plurality of pulse width limiters arranged in series to thereby provide a series of pulse width limiters, and wherein a first pulse width limiter limits the pulse width of the received known clock signal to generate the first intermediate signal, and wherein a last pulse width limiter in the plurality of pulse width limiters outputs the reset signal.
