In this short video, how to generate two 90 degree phase shifted digital signals using D Flip-Flops is explained.
The video also explains the alternate way of generating the same signal at the end.

Please note:
At 3:13, in the 4-bit Johnson Counter Circuit, the output should be connected from Q4' to the D input of the first flip-flop. By mistake, it is connected from Q4 to D input.
