PURPOSE:To perform high-speed transmission, by driving a master and a slave frequency divider by a push-pull inverter capable of generating two driving signals which are out of phase with each other while their phase difference is almost eliminated. CONSTITUTION:A signal S1 appearing at the output side of a transistor TR29a is delayed in phase behind a signal S2 appearing at the output side of a TR28a by as much as it passes through the TR29a. Those signals S1 and S2 are supplied to TRs 31b and 32a, and 32b and 31a of the push-pull inverter circuit 3 to obtain output signals S2 and S4 at the output sides of the TRs 31a and 32a. Then, this circuit 3 outputs signals phi and phi' which are in phase with each other. Those signals phi and phi' are frequency-divided by 2 through the frequency dividing circuit 4 consisting of latch circuits 41 and 43, and a sampling circuit 42 and then supplied to the next stage through a sense amplifier 5. |
