Live Demonstration: Real-Time High-Amplitude Signal Acquisition with 2-Channel Modulo ADC
Modulo analog-to-digital converters (ADCs) offer a potential solution to the clipping challenges in conventional ADCs by folding signals that exceed the threshold. This makes them suitable for high-amplitude signal acquisition in wide dynamic range applications. In this demonstration, we present a 2-channel modulo ADC system implemented on a field-programmable gate array (FPGA) with an integrated real-time recovery algorithm. By managing both signal folding and recovery entirely in hard-ware, the system ensures low-latency processing. The FPGA efficiently handles high-bandwidth signals, making it a promising option for applications that require robust performance in high-amplitude signal environments.
