Timing parameters of a flip flop
There are basically 3 types of factors which affect the working of a flip flop: 1. Setup Time: This is defined as minimum amount of time required for which an input should be stable just before the clock transition occurs. Suppose we have a positive edged JK flip-flop and setup time is t= 1ns seconds. If […]
