The Analog/Mixed-signal IC Design Engineer will be a key member in a small, dynamic IC Design team that develops high speed mixed-signal designs for coherent optical communications products. This team has track record of developing ultra-high speed (>100 Gsps) data converters in latest FinFET nodes. This engineer will architect, design, layout, test and productize ultra-deep sub-micron based products.

Essential Responsibilities:

  • Responsible for analog circuit, layout design and testing of analog/mixed signal circuitry for high speed (>25GS/s) and high accuracy Analog designs
  • Work with the mixed-signal and system teams to specify the requirements
  • Candidate (depending on experience) might be required to lead a large block on a complex chip and mentor some engineers.
  • Peer review of complex IC designs
  • Solid design methodology from conception to production
  • Work with packaging and hardware design team to ensure signal and power integrity specifications are met

Minimum Qualifications, Experience, Skills, Education and Certifications:

  • Typically requires a BSEE degree and 9 years of experience or an MS degree and 6 years of experience or a PhD and 3 years of experience. Outstanding fresh PhD graduates would be considered as well.
  • Design, simulation and measurement of high-speed ICs in at least 3 areas below:
  • High speed Time-interleaved ADC
  • Tuned high frequency circuits
  • Resonant Clock Circuits, Clock distribution and Low power Clocking Techniques
  • Digital fractional-N phase-locked loop (PLL)
  • High speed Time-interleaved DAC and Output Drivers
  • Digital calibration of analog circuit imperfections
  • Voltage Regulators
  • Opamps and Programmable Gain Amplifiers
  • Equalization techniques

Highly Desired Skills:

  • Experience with FinFET technology.

a) Passive component design: inductors, transformers, transmission-lines

b) High-frequency layout experience a plus.

c) Floorplanning (power/ground, digital/analog signal routing etc.)

d) Custom transistor layout.

e) Characterization over PVT (monte-carlo analysis)

f) Electromigration analysis (using Totem, Voltus-Fi or equivalent)

g) Power and IR drop analysis

  • Laboratory Validation:

a) Solid ESD laboratory practices and methodology

b) Construction of test setup to test specific circuitry

  • Software Experience:

a) Cadence (virtuoso)

b) Spectre/APS/SpectreX

c) Layout validation tools (Virtuoso or Calibre)

d) Post-layout Extraction (Virtuoso or Calibre)

e) EMX

f) Mixed-signal simulations in AMS

g) Matlab

  • Collaborative team player who can work independently.
  • Possessing a track record of innovation. Publications are a plus.

Why Cisco

#WeAreCisco, where each person is unique, but we bring our talents to work as a team and make a difference powering an inclusive future for all.

We embrace digital, and help our customers implement change in their digital businesses. 

But Digital Transformation is an empty buzz phrase without a culture that allows for innovation, creativity, and yes, even failure (if you learn from it.)

Day to day, we focus on the give and take. We give our best, give our egos a break, and give of ourselves (because giving back is built into our DNA.) We take accountability, bold steps, and take difference to heart. Because without diversity of thought and a dedication to equality for all, there is no moving forward.

So, you have colorful hair? Dont care. Tattoos? Show off your ink. Like polka dots? Thats cool. Pop culture geek? Many of us are. Passion for technology and world changing? Be you, with us!
