Examining and Evaluating Comparator Circuit Performance Experimentally at Various Technology Nodes

In the realm of analog circuit design, the study of low-power, high-precision, and high-speed, comparator circuits holds paramount significance. Dynamic comparators, recognized as pivotal elements in the construction of ADC's and sense amplifiers, play a crucial role in achieving optimal precision, minimal offset voltage, low power consumption, faster operation, less power consumption, and greater dependability. However, no single circuit can comprehensively offer all these desirable attributes. This research paper delves into the analysis of propagation delays, power dissipation, energy, offset voltage, and noise. Through this study, readers can derive analytical expressions to comparator performance. To validate the findings, extensive simulations were conducted using cadence virtuoso in 180nm, 90nm, and 45nm CMOS technology nodes.
