FLIPFLOP USING COMPLEMENTARY CLOCKING AND PRESCALER USING THE SAME

摘要

PURPOSE: A flipflop using complementary clocking and a prescaler using the same are provided to improve the current driving capacity by using the complementary relation between an NMOS transistor and a PMOS transistor. CONSTITUTION: A first p-type transistor(mp11) is connected between a supply voltage supply unit and the first node to receive data. A second p-type transistor(mp12) is connected between the first and the second nodes to receive the first clock. A first n-type transistor(mn11) is connected between the second node and the ground to receive the data. A third p-type transistor(mp13) is connected between the supply voltage supply unit and the third node. A second n-type transistor(mn12) is connected between the third and the fourth nodes to receive the first clock. A third n-type transistor(mn13) is connected between the fourth node and the ground. A fourth p-type transistor(mp14) is connected between the supply voltage supply unit and an output terminal. A fourth n-type transistor(mn14) is connected between the output terminal and the ground to receive the second clock. A fifth n-type transistor is connected between the first and the second nodes to receive the second clock. A fifth p-type transistor is connected between the third and the fourth nodes to receive the second clock.
