Description
This work presents the simulation and conceptual design of an electronic data acquisition system for the characterization of ultra-short pulses generated with high repetition rate. The project is developed within the framework of the cSTART initiative at the Karlsruhe Institute of Technology (KIT) and will be evaluated at the KArlsruhe Research Accelerator (KARA).
The primary focus of this study is the accurate detection and analysis of short time signals with a bandwidth in the order of 100 GHz. Due to their high analog bandwidth, digitization of such signals require very high sample rate digitizers to maintain signal integrity.
To address these challenges, a detailed simulation of the required circuitry is presented, demonstrating how the bandwidth of the analog signal can be effectively reduced, thereby enabling digitization at a significantly lower sample rate. The simulation model incorporates realistic component parameters to ensure a high degree of correspondence between the simulated and the expected physical response. These simulations not only confirm the theoretical feasibility of the approach but also serve as a refined basis for subsequent hardware development. The insights gained from this simulation study lead to a concrete design foundation and enable the realization of an upcoming physical prototype, whose real-world behavior under practical operating conditions will be used to verify and further substantiate the simulation results.
