Job Summary

The primary objective of this project is two-fold: first, to innovate low-phase and amplitude noise frequency synthesis techniques spanning from radio frequencies to the optical regime; and second, to develop advanced analog and digital measurement systems for precise phase and time characterization.  This capability is vital to the NIST mission, enabling the creation of sophisticated instrumentation with significantly lower noise floors and higher throughput—essential requirements for characterizing next-generation atomic clocks and ultra-low-noise oscillators.

To achieve these rigorous performance standards, the work requires a synergistic approach that bridges the analog and digital domains.  The research will focus on integrating high-performance analog front-ends—critical for signal purity—with modern FPGA-based digital signal processing.  By leveraging the low-noise characteristics of precision analog design alongside the flexibility of digital analysis, this project aims to create robust measurement architectures that outperform traditional single-domain solutions.

This position is part of the National Institute of Standards and Technology's (NIST) Professional Research Experience Program (PREP).  NIST recognizes that its research staff may wish to collaborate with researchers at academic institutions on specific projects of mutual interest, thus requires that such institutions must be the recipient of a PREP award.  The PREP program requires staff from a wide range of backgrounds to work on scientific research in many areas.  Employees in this position will perform technical work that underpins the scientific research of the collaboration.
CU is an Equal Opportunity Employer and complies with all applicable federal, state, and local laws governing nondiscrimination in employment. We are committed to creating a workplace where all individuals are treated with respect and dignity, and we encourage individuals from all backgrounds to apply, including protected veterans and individuals with disabilities.

Who We Are

PREP is a special partnership between the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder.  PREP provides research opportunities to CU undergraduate and graduate students, as well as researchers with a Bachelor's, Master's, or PhD in NIST labs to gain research experience alongside NIST scientists.
 
The particular group that needs a researcher is the Time and Frequency - HQ Group at NIST.

What Your Key Responsibilities Will Be

  • Design and construct low phase frequency synthesizers and oscillators.
  • Amplitude and phase noise metrology.
  • PCB layout and design of measurement system circuits.
  • Develop FPGA based measurement system firmware.
  • Presenting results at internal meetings, and occasional meetings with external stakeholders.
  • Ensuring that results, protocols, software, and documentation have been archived or otherwise transmitted to the larger organization.
