Abstract:
A driver circuitry connected to a power voltage supply line supplying a power voltage and also connected to a driving voltage supply line supplying a driving voltage, said driver circuitry comprising:a first circuit having a first input terminal receiving at least a first reference voltage and a second input terminal connected to said driving voltage supply line for feeding said driving voltage back to said second input terminal for comparing said driving voltage with said reference voltage, and said first circuit having an output terminal for outputting an output voltage which accords to a difference in potential between said driving voltage and said reference voltage;a switching device connected between said power voltage supply line and driving voltage supply line, said switching device having a control terminal connected to said output terminal of said first circuit for receiving said output voltage so that said switching device performs ON-OFF switching operations in accordance with said output voltage; anda high speed driving device connected to said control terminal of said switching device for turning said switching device ON at a higher speed than when said switching device turns ON in accordance with said output voltage from said first circuit.
