The D flip-flop is widely used, and known as a "data" flip-flop. The D flip-flop captures the value of the D-input at a definite portion of the clock cycle (such as the rising edge of the clock). That captured value becomes the Q output. At other times, the output Q does not change.
A shift register is a type of digital circuit using a cascade of flip-flops where the output of one flip-flop is connected to the input of the next. They share a single clock signal, which causes the data stored in the system to shift from one location to the next.
The straight ring counter has the logical structure shown here: Instead of the reset line setting up the initial one-hot pattern, the straight ring is sometimes made self-initializing by the use of a distributed feedback gate across all of the outputs except that last, so that a 1 is presented at the input when there is no 1 in any stage but the last.

A multivibrator is an electronic circuit used to implement a variety of simple two-state [1] [2] [3] devices such as relaxation oscillators, timers, latches and flip-flops.The first multivibrator circuit, the astable multivibrator oscillator, was invented by Henri Abraham and Eugene Bloch during World War I.
In a real flip flop this will cause the output to go to a 1. However, in this model it will not occur because the always block is triggered by rising edges of set and reset – not levels. A different approach may be necessary for set/reset flip flops. The final basic variant is one that implements a D-flop with a mux feeding its input.
The clk input to the PMOS will charge the output node to high when clk is low. If the D input is already high, there is no need to charge the output to high again. Thus, if one can control this behaviour there can be a power reduction in the flip-flop. To control the internal node in the precharge path, a control switch is used as shown in Fig 1.
An asset flip is a type of shovelware in which a video game developer purchases pre-made assets and uses them to create numerous permutations of generic games to sell at low prices. [1] Such games tend to be viewed by gamers as uncreative, [ 1 ] and as diverting attention from less popular high-quality titles.
