FPGA Power Supply Considerations
An FPGA is a device that offers many logic elements as well as other functionality such as transceivers, PLLs, and MAC units for complex processing. FPGAs are becoming very powerful, and the need to power the devices effectively is a key part of the design. A straightforward power supply design process can significantly reduce the number of required design iterations for the OEM designer. This application note looks at the various types of voltage regulators used to power FPGAs, offers guidance on how and where to place them on the PCB, and takes the reader step-by-step through a design example.
