Extropic is seeking a Principal Analog/Mixed Signal Engineer with experience in CMOS technology.

About the role

This role involves the design of analog and mixed-signal circuits and supporting hardware development.

What you'll do

Design analog blocks including comparators, op-amps, reference/bias generation, LDO regulators, filters, switch-cap, and data converters.
Design and layout high-speed analog circuits such as frequency dividers, oscillators, and PLLs.
Conduct comprehensive simulations using Cadence for PEX, Monte-Carlo, and Corner analysis.
Support project tape-out verification, including DRC, ERC, and LVS.
Perform pre-silicon validation and top-level mixed-signal design simulations.
Conduct lab-testing of mixed-signal circuits using signal generators, spectrum analyzers, and oscilloscopes.

5+ years relevant experience in Analog/Mixed Signal Engineering.
Solid understanding of CMOS device characteristics, noise, mismatch, and linearity.
In-depth knowledge of analog mixed-signal concepts including noise, linearity, stability, low-power, and low-noise techniques.
Deep understanding of reliability issues and layout effects such as electro-migration (EM), and strategies to mitigate them.
Experience designing with modern CMOS technology.

Skills: CMOS, op-amp, LDO regulators, PLLs, Cadence
