a timing signal generator which can operate stably even when , or directly after , a power supply is switched on . the generator is of the type having a first dynamic delay circuit for generating a first timing signal in response to said input control signal and a second dynamic delay circuit for generating a second timing signal in response to the first timing signal , and is featured by a first transistor connected between the output of the first dynamic delay circuit and a voltage terminal with a gate connected to the input of the first dynamic delay circuit and a second transistor connected to the output of the second dynamic delay circuit and the voltage terminal with a gate connected to receive the first timing signal .
