WebCMOS D-Latch Implementation • A D-latch is implemented, at the gate level, by simply utilizing a NOR-based S-R latch, connecting D to input S, and connecting D’ to input R with an inverter. – When CLK goes high, D is transmitted to output Q (and D’ to Q’) – When CLK goes low, the latch retains its previous state • The D latch is ... WebA flip flop is the fundamental sequential circuit element, which has two stable states and can store one bit at a time. It can be designed using a combinational circuit with feedback and a clock. D Flip-Flop is one of that Flip Flop that can store data. It can be used to store data statically or dynamically depends on the design of the circuit.
