Senior/Principal Analog Mixed-Signal Design Engineer, Optical Receiver
Analog & Mixed-Signal Design
High-speed parallel optical links built from arrays of microLED transmitters and photodetector receivers.
About the role
Avicena is seeking an analog mixed-signal engineer to design receiver front-ends for high-speed parallel optical links built from microLED transmitters and photodetector receivers. The role owns circuits from specification through post-layout signoff and silicon correlation.
What you'll do
- Design and simulate receiver circuits including photodetector interfaces, transimpedance amplifiers, limiting and post-amplifiers, equalization, comparators, slicers, offset cancellation, and signal detection.
- Analyze noise, bandwidth, sensitivity, crosstalk, and power per lane across PVT corners and Monte Carlo.
- Design calibration and trim circuits, and define their control interface with the digital team.
- Collaborate with layout on floorplans, matching, and parasitic-sensitive routing for dense receiver arrays, and execute post-layout extraction and verification.
- Deliver behavioral models in Verilog-A or real-number models and correlate them with transistor-level results.
- Support silicon bring-up and correlate measurements with simulation results.
What you'll need
- MS or PhD in Electrical Engineering (or BS with equivalent experience) and 5+ years of analog/mixed-signal design experience.
- Track record of taped-out high-speed receiver circuits such as TIAs, CTLEs, limiting amplifiers, or comparators for optical or wireline links.
- Design experience in FinFET or other advanced CMOS processes.
- Proficiency with Cadence Virtuoso and Spectre, including noise, AC, transient, and Monte Carlo analysis.
- Experience taking blocks through post-layout extraction and signoff.
Nice to have
- Experience with optical receivers or photodiode interfaces.
- Experience with multi-Gb/s wireline receivers or arrays of parallel lanes.
- Behavioral modeling in Verilog-A or SystemVerilog real-number models.
- Hands-on lab characterization experience.
- Experience with MATLAB or Python for analysis and automation.
- 10+ years of experience with technical leadership of receiver designs through production.
Skills: TIA, optical receiver, FinFET, Cadence Virtuoso, Spectre, post-layout signoff
