| Summary: | The present invention pertains to a pulse generator, and more specifically, the invention relates, particularly but not exclusively, to a pulse generator that is independent of supply voltage and useful with non-volatile semiconductor memories, the description which follows covering this field of application for convenience of explanation only.
A pulse generator of a type that includes at least one current mirror connected between first and second voltage references and to at least one initiation terminal receiving a pulsive-type initiating signal, connected to a load terminal receiving a load signal, and connected to an output terminal providing an output signal. The pulse generator further includes at least one logic gate having one input terminal connected to an internal control circuit node of the current mirror, having another input terminal connected to receive the initiating signal, and having an output terminal connected to the output terminal of the pulse generator; at least one regulator circuit connected between the current mirror and the second voltage reference and feedback connected to the output terminal; and at least one conductive-type transistor connected between the current mirror and the regulator circuit; the output terminal of the pulse generator delivering a retarded pulsive-type output signal that is independent of the supply voltage and exhibits the same dependency on temperature as the regulator circuit. |
