Intrusion Detection System (IDS) must be developed based on latest live traffic dataset. This will facilitate the study on new attributes of current threat. Once again, researchers are locked on the same vicious circle of inability to access live traffic dataset. This is coupled with public domain logged dataset may not be useful for a new threat research. Due to these standing hurdles, Pseudo Random Binary Sequence (PRBS) is used to generate synthetic dataset in IDS studies. One of its components is the Digital to Analog (D/A) converter. There are two types of D/A implementations; 1) through Weighted and 2) R2R resistors. This paper compares the advantages and the disadvantages of designing D/A converter by using the abovementioned resistors. It is advisable to opt for R2R version over Weighted Resistor since it is easier and practical to choose the multiple types of resistors during circuit design process. Furthermore, the shifted parallel output from the circuit can be synchronized by the proposed PLL circuit. © 2023 IEEE.
