The growing number of high-performance FPGA and ASIC applications that are driven by the increased bandwidth of wireless networks and data centers demand for power regulators with high power density, fast load transient response, and high efficiency. AMD Xilinx Zynq UltraScale+ RFSoCs integrate multi-giga-sample RF data converters and soft-decision forward error correction (SD-FEC) into a SoC arch...

Switched-mode power supplies (SMPS) have the advantage of high efficiency compared to traditional low-dropout (LDO) regulators. Due to its switching nature, a SMPS emits noise at its switching frequency and its harmonics. This article illustrates the procedure of designing filtering to achieve ultra-low output voltage noise with SMPS regulators. Single-stage capacitive filter is commonly used for ...

Powering modern applications requires high currents, precise transient control, and a flexible voltage set-up. In particular, field-programmable gate array (FPGA) power specifications often come with rigid requirements regarding output voltage (VOUT) accuracy, where the absolute VOUT accuracy must be around ±1.5%,regardless of temperature variations and aging. Some manufacturers’ load regulation s...

Powering the core rails of high-end field-programmable gate arrays (FPGAs) and application-specific integrated circuits (ASICs) requires high current as well as precise transient control. In recent years, the rapid advancements in FPGAs, ASICs, and related systems have necessitated significant updates to power delivery regulations to address the increased complexity. These designs demand a delicat...
