Conventional delay circuits with one input cannot perform the task of generating delay between the input and output while operated at GHz frequencies. In addition, by switching 1 GHz signal at the input of conventional delay circuits, the signal suffers from distortion inside the chip. Whereas, the use of a resistance can control the delay and so becomes the cause of voltage loss inside the chip. The resistance also acts as a filter, which eliminates higher frequency signals and suppresses the operating frequency of a signal. Considering all these pros and cons, this work suggests a method of designing a differential scheme made of two identical drivers and a comparator for generation of delay signal from the original signal, thus enhancing the operating frequency from 1 Gbps to 4 Gbps at 180 nm process technologies.
