PROBLEM TO BE SOLVED: To reduce a circuit expense for function groups and a circuit expense for a communication route which extends between the function groups by making a whole driving signal generating circuit a module and dividing the driving signal generating circuit into each function group. SOLUTION: A starting/stopping module 10 receives a clock signal Clk and a switch-on duration value Data then generates a starting signal Start and a stopping signal Stop. These both signals, a coincidental signal Sgn and two driving signals S2, S4 which designate a present switching state are prossessed by a branch selecting module 11 to generate two switching signals Tg1, Tg2. The first switching module 12 receives the first switching signal Tg1, then generates both driving signals S1 and S2 from the first switching signal Tg1, on the other hand, driving signals S3 and S4 are conducted from the second switching signal Tg2 by the second switching module 13. |
