The problems with S-R flip flops using NOR and NAND gate is the invalid state. This problem can be overcome by using a bistable SR flip-flop that can change outputs when certain invalid states are met, regardless of the condition of either the Set or the Reset inputs. For this, a clo...
The logic circuits I used to create the RS flip-flop are NAND gates. You can learn more about NAND gates, as well as many other basics of digital electronicshere. For now, however, it's sufficient to understand that a NAND gate’s output only goes high when its two inputs are low. ...
SR Flip Flop to D Flip Flop As shown in the figure, S and R are the actual inputs of the flip flop and D is the external input of the flip flop. The four combinations, the logic diagram, conversion table, and the K-map for S and R in terms of D and Qp are shown below. SR...
Such flip flops can be made simply by cross coupling two inverting gates either NAND or NOR gate. Figure 1(a) shows an RS flip flop using the NAND gate and Figure 1(b) shows the same circuit using NOR gate. Figure 1: Latch R-S Flip Flop Using NAND and NOR Gates To describe the ...
MAX17014 Low-Cost Multiple-Output Power Supply for LCD TVs On the rising edge of the internal clock, the controller sets a flip-flop, turning on the n-channel MOSFET and applying the input voltage across the inductor. The current through the inductor ramps up linearly, storing energy in its...

The D flip flop is the most important flip flop from other clocked types. It ensures that at the same time, both the inputs, i.e., S and R, are never equal to 1. The Delay flip-flop is designed using a gatedSR flip-flopwith an inverter connected between the inputs allowing for ...
A 2.5-V 45-Gb/s decision circuit using SiGe BiCMOS logic A 45-Gb/s BiCMOS decision circuit operating from a 2.5-V supply is reported. The full-rate retiming flip-flop operates from the lowest supply voltage of an... TO Dickson,R Beerkens,SP Voinigescu - 《IEEE Journal of Solid ...

(flip-flop). Yet another delay circuit is shown as circuit 53 (FIG. 4C), where a generic digital frequency divider CD1 is triggered by the rising edge of the sync pulse through a generic NAND gate N2. The other NAND input is clocked by a frequency source and when the counter CD1 ...
