Abstract
A signal generating circuit which generates an output signal in a dynamic manner without being influenced by noise is disclosed. The signal generating circuit comprises a first transistor connected between a power voltage source and an output node, and second and third transistors connected in series between the output node and a ground voltage line. A first signal which assumes an active level in a first period and an inactive a second period subsequent to the first period, is applied to a gate of the second transistor, and a second signal which assumes an active level for a first time duration in the second period and an inactive level in a remaining second time duration in the second period and the first period, is applied to a gate of the first transistor. A third signal which assumes an active level in the first period and an inactive level in the second time duration, is applied to a gate of the second transistor.
