CMOS flip-flops often use transmission gates (a parallel combination of NMOS and PMOS) as electronic switches. These gates control the flow of data based on the clock signal ( CLKcap C cap L cap K The Master Section: When the clock is low ( ), the Master latch locks the data, and

A CMOS flip-flop utilizes both and p-type (PMOS) transistors in a complementary arrangement. Unlike older TTL (Transistor-Transistor Logic) designs, CMOS circuits draw significant power only during the switching process. In a steady state, one of the transistor types is always "off," creating a high-impedance path that results in near-zero static power dissipation. Design of a CMOS D Flip-Flop
