Clock driver circuit
Abstract
A clock driver circuit comprises a first driver including first and second inverters cascaded between an input terminal and a first output terminal for outputting a non-inverted signal delayed from the clock signal applied to the input terminal by a delay amount corresponding to two stages of inverters. The clock driver circuit also comprises and a second driver including third, fourth and fifth inverters cascaded between the input terminal and a second output terminal and a sixth inverter connected between the input terminal and the second output terminal. With this arrangement, a first signal delayed from the clock signal applied to the input terminal by a first delay amount corresponding to the third, fourth and fifth inverters, is synthesized by a wired-OR at the second output terminal with a second signal delayed from the clock signal applied to the input terminal by a second delay amount corresponding to the sixth inverter. Thus, a synthesized inverted signal delayed from the clock signal applied to the input terminal by a delay amount corresponding to two stages of inverters, is outputted from the second output terminal.
