As we are shrinking the process node and reducing nominal voltages, voltage margins available at the transistors are shrinking. Higher IO data rate requirements with each new generation is exacerbating the system design. Modern systems are looking for all day battery life on laptops and tablets, while some systems needs to be optimized for cost. This paper compares the voltage regulator implemented on mother board against a fully integrated voltage regulator on silicon and identifies the scenario when one can be chosen over the other. Lab data for both the implementations will also be shared.
Takeaway
Voltage Margins are squeezed with increased data rates and lower voltage. Based on the system, cost and power and performance requirements, designer has to choose between using an Discrete Voltage Regulator on board or a Fully Integrated Voltage Regulator on die
Intended Audience
Knowledge about power integrity, power electronics, voltage regulator, system design, packaging, PCB design, power and performance metrics
