Abstract
The clock-generating circuit for generating a clock signal, includes a ring oscillator having an odd number of inverters connected in a ring configuration. The ring oscillator is activated to generate a clock signal when an activating signal is at a first level and is de-activated to cease generation of the clock signal when the activating signal is at a second level. A latch circuit is connected to an output node of the ring oscillator, and holds a level of the output node of the ring oscillator in response to transition of the activating signal from the first level to the second level. When the activating signal is lowered from the H level to the L level, the level of the clock signal is latched such that generation of a glitch in the clock signal will be prevented from occurring.
