Abstract:
1. A driver circuit comprising: first and second series-connected three-terminal active elements, each of said first and second three-terminal active elements having an amplification function and first, second, and third electrodes, the second and third electrodes of each three-terminal active element being series-connected between first and second potentials; first and second delay means which receive the same input signal; an output load coupled to an end of the first and second series-connected three-terminal active elements, wherein outputs of said first and second delay means are respectively connected to the first electrodes of said first and second three-terminal active elements, a delay amount of said second delay means is larger than a delay amount of said first delay means, and the delay amount of said first delay means is a finite value including zero wherein the driver circuit further comprises at least one three-terminal active element which is series-connected to said first and second three-terminal active elements on a side close to the second potential between the first and second potentials, and at least one further delay means which receives the same input signal as in said first and second delay means, an output of said further delay means is connected to a first electrode of said third three-terminal active element, and a delay amount of said further delay means is larger than the delay amount of said second delay means, and increases as the number of three-terminal active elements increases.
