Internship Analog-Mixed-Signal Design for Power Line Communication

Design and Control of Resonant Charge Recovery Circuits for High Voltage Ground Modulation

Overview:

The ACC department in Eindhoven is part of the worldwide Central Technology Organization (CTO) of NXP that supports all NXP Business Lines by architecting designing and delivering the analog and mixed-signal building blocks that are at the heart of competitive NXP products. You will be working in a diverse team with world-class subject matter specialists where there is always room for new ideas and innovation.

ACC employs about 250 analog/mixed-signal design specialists located in the Netherlands India Sweden and US who take full responsibility for IP design and system integration.

Assignment:

The project focuses on the design and exploration of resonant chargerecovery circuits for highvoltage groundmodulation applications. These circuits use a CLC resonant tankcombining load capacitance inductance and configurable buffer capacitancesto efficiently charge and discharge the modulated ground node while recovering energy that would otherwise be dissipated.

You will investigate feedforward and closedloop control schemes for amplitude shaping and slope control including the use of peakdetection ADCbased digital regulation and tunable buffercapacitor configurations. The objective is to understand and design the resonant system that can achieve predictable voltage swings controlled rising/falling slopes and improved energy efficiency across modulation frequencies. Ultimately your work will contribute to developing an improved control architecture for resonant chargerecovery circuits that minimizes power consumption.

Your Responsibilities:

• Develop InDepth Understanding of Resonant ChargeRecovery Systems.
• Build behavioral and circuitlevel models of the resonant chargerecovery architecture.
• Design circuit blocks such as resonant switches buffercapacitor tuning networks peakdetection circuits and digital amplitudecontrol logic.

Your Profile:

• MSc student in Electronic Engineering or related field with an emphasis on IC design
• Affinity with the state of art analog design/verification flow and tools preferably with Cadence tooling
• Creative and positive mindset
• Flexible and eager for new challenges
• Excellent communication and documentation skills in English
• Desire for a career in analog/mixed-signal integrated circuit design

Duration

This internship can also be suitable for a thesis project. It is a fulltime assignment (40 hours per week) with a minimum duration of six months with the possibility to extend. Please note that to be considered for an internship or working student position at NXP you must be enrolled as a student for the entire duration of the assignment.
