Mixed-Signal IC Designer - US-CA-Santa Clara-Bldg 4-Keysi, United States
$164,430 - $274,040 USD yearly
Originally posted 28 August 2026 by the employer — open 12 days.
About the role
You will join a team developing custom ASIC data converter solutions in GHz applications, implementing core ADC and DAC structures, streaming I/O data paths, or complex measuring and emulating communication transceiver ASICs in CMOS and BiCMOS technologies.
What you'll do
- Design high-speed analog and mixed-signal circuits.
- Implement transistor level design and physical design.
- Design mixed-signal building blocks and integrated systems such as PLLs, DACs, Serializers, ADCs, or wideband amplifiers.
- Troubleshoot and drive to root cause on difficult problems.
What you'll need
- PhD in Electrical Engineering with thesis work on mixed-signal IC design, or MS in Electrical Engineering with substantial experience in IC design.
- Experience in designing high-speed analog and mixed-signal circuits in CMOS or BiCMOS technologies.
- Experience with transistor level design and physical design.
- Experience with mixed-signal building blocks and integrated systems, such as PLLs, DACs, Serializers, ADCs, or wideband amplifiers.
Nice to have
- Experience in mixed-signal circuit design through a complete design and fabrication cycle.
- Strong working knowledge of GHz clock, DAC, and ADC circuits.
- Solid background in device modelling, thermal design, and IC package design.
- Understanding of semiconductor technologies, devices, and parasitics.
- Understanding of signal integrity and EM issues.
- Experience with at least the 65 nm process node.
- Experience with mixed-mode simulation of analog and digital blocks, including behavioral modelling of analog circuits, using tools like Verilog or Verilog A.
- Familiarity with programming and scripting languages for design, simulation, and testing automation.
- Ability to perform hands-on measurements using test and measurement equipment.
- Experience with synthesized digital design flows, using RTL descriptions to deliver verified netlists for physical synthesis.
