Lead Analog Circuit Designer (Planar CMOS)

Job Description:

We are seeking a Lead Analog Circuit Designer with hands-on experience in planar CMOS technologies. The ideal candidate selects and tailors circuit topologies to the target application (consumer, automotive, aerospace, industrial), designs for robust performance under parasitics and variability, and ensures reliability across process, voltage, and temperature (PVT) with consideration of long-term aging mechanisms (BTI/HCI).

Key Responsibilities

• Translate system requirements into block-level analog specifications; choose appropriate topologies per application class (e.g., low-power consumer, high-reliability automotive, mission/temperature-critical aerospace).
• Design, simulate, and verify analog IP (e.g., references/bandgaps, bias, amplifiers/OTAs, comparators, ADC/DAC front ends, LDOs, clocking/PLL sub-blocks) in planar CMOS nodes.
• Account for parasitic effects early (wiring resistance, coupling capacitance, device parasitics), collaborate closely with layout, and drive post-layout (PEX) correlation to meet spec.
• Ensure robustness across PVT variations, mismatch (Monte Carlo), supply ripple/noise (PSRR), and temperature range; implement compensation and guard-banding.
• Model and mitigate reliability/aging drifts (BTI/HCI) on key parameters (Vth, gm, offset, bias currents) and reflect lifetime targets in design margins.
• Define and execute verification plans: corners, Monte Carlo, noise, linearity, transient, stability (phase margin), startup, ESD and latch-up checks in partnership with reliability/ESD teams.
• Collaborate with layout on matching strategy (common-centroid/interdigitation, dummies), symmetry, and current density/EM considerations; review DRC/LVS/ERC outcomes affecting electrical intent.
• Document assumptions, models, and sign-off criteria; present design reviews and contribute to reusable templates and best practices.

Nice to Have

• Experience in safety-/reliability-focused product spaces (automotive, aerospace, industrial) and associated design assurance practices.
• Scripting/automation (e.g., Python, SKILL) for corners, data mining, and reporting.
• Lab bring-up and silicon validation of analog IP; data analysis and correlation to simulation.
