Lead Tech – Analog and Mixed-Signal (AMS) IC Design

Lead Tech is the guardian of the technical architecture and performance of integrated circuits (ICs). They drive technological choices and oversee the entire implementation process, from initial specifications to GDSII (tape‑out). They ensure design robustness against Process, Voltage, and Temperature (PVT) variations in a specific cryotemperature environment. He is also responsible for managing the team, subcontractors, and service providers.

Technical Challenges

Architecture & Specification: Define the architecture for critical blocks (ADC/DAC, PLL, PMU, filters, amplifiers, Mux, control …) and translate system requirements into circuit‑level specifications.

Design & Simulation: Supervise transistor‑level design, corner simulations, noise analysis, and mismatch analysis. A specific point of our designs is the very low operating temperature (100 m

K to 4 K).

Layout Guidance: Lead layout engineers on matching issues, parasitic coupling, and signal integrity.

Mixed‑Signal Verification (AMS): Define verification plans for operation at the interface between the analog and digital domains.

Post‑Silicon Validation: Collaborate with test teams to characterize chips in the lab and analyze measurements and tests.

R&D & Innovation: Evaluate new architecture and operating temperature partitioning and protect innovations through patent filing.

Technical Expertise & Skills

Scientific Expertise: Semiconductor Physics, Block Design, Signal Integrity & ESD, Modeling (Verilog‑A, MATLAB), Architecture study.
