Understanding the Role of Analog Components in FPGA Designs
While Field-Programmable Gate Arrays (FPGAs) are fundamentally computation devices, several current applications increasingly require integration with analog circuitry. This calls for a detailed understanding of the part analog parts play. These circuits, such as amplifiers , regulators, and data converters (ADCs/DACs), are crucial for interfacing with the physical world, managing sensor readings, and generating analog outputs. Specifically , a radio transceiver constructed on an FPGA may use analog filters to reject unwanted interference or an ADC to change a voltage signal into a discrete format. Hence, designers must precisely analyze the interaction between the digital core of the FPGA and the analog front-end to attain the desired system performance .
