Patent ID: 7106038

Claim:
An apparatus for generating an output signal with an adjustable pulse width that is responsive to an input signal, comprising: a ramp circuit that is arranged to provide a ramp signal that has a slope, wherein the slope of the ramp signal is responsive to the input signal; a switch control circuit that is arranged to provide a switch control signal in response to the output signal; a switch circuit that is arranged to cooperate with the ramp circuit such that the ramp signal is reset to an initial condition in response to the switch control signal; a comparator circuit that is arranged to provide a comparison signal in response to a comparison between the input signal and the ramp signal; and a latch circuit that is arranged to: set the output signal to a first logic level in response to an oscillator signal, and reset the output signal to a second logic level in response to the comparison signal, wherein the first logic level and the second logic level are inverse with respect to one another.
