Job Overview

We are looking for an experienced Analog Circuit Design Engineer with 4+ years of experience in Analog/Mixed-Signal circuit design, particularly in high-speed interface and communication protocols.

The ideal candidate should have strong expertise in transistor-level circuit design, high-speed analog circuit development, SPICE simulations and performance optimization. Experience working on advanced TSMC technology nodes and high-speed interfaces such as PCIe, USB, Ethernet, DDR and SerDes is highly desirable.

Key Responsibilities

- Design, develop and optimize transistor-level analog and mixed-signal circuits for high-speed interface applications.
- Work on high-speed circuit blocks involving SerDes, PLL, CDR, DLL, clocking circuits and equalization techniques.
- Develop analog circuit architectures for high-speed protocols such as PCIe, USB, Ethernet, DDR and other high-bandwidth interfaces.
- Perform transistor-level circuit design, simulation, debugging and optimization.
- Conduct pre-layout and post-layout simulations to validate circuit performance.
- Perform PVT corner analysis, Monte Carlo simulations and statistical analysis.
- Optimize circuits for power, performance, area (PPA), jitter, noise and signal integrity.
- Work on circuit design and implementation using advanced TSMC technology nodes.
- Collaborate with layout, verification and physical design teams for successful block integration.




- Analyze and resolve circuit-level issues related to timing, stability, power consumption and performance.
- Support silicon validation and characterization activities, where required.

Required Technical Skills
- 4+ years of experience in Analog/Mixed-Signal Circuit Design.
- Robust hands-on experience in transistor-level circuit design.
- Experience with high-speed interface protocols such as PCIe, USB, Ethernet, DDR or SerDes.
- Solid understanding of high-speed analog circuit blocks such as PLL, CDR, DLL, TX/RX, equalizers and clocking circuits.
- Hands-on experience with SPICE-based simulation tools such as Cadence Spectre, HSPICE, FineSim or PrimeSim.
- Experience in PVT, Monte Carlo, transient, AC and DC simulations.
- Experience working on advanced TSMC technology nodes.
- Good understanding of CMOS fundamentals, device characteristics, noise, jitter and signal integrity.
- Experience with Cadence Virtuoso and schematic design environments.

Preferred Skills
- Experience with TSMC advanced nodes such as 3nm, 5nm, 7nm or 16nm.
- Strong understanding of high-speed SerDes architecture and circuit design.
- Exposure to PCIe Gen4/Gen5/Gen6, USB 3.x/4, DDR4/DDR5 or high-speed Ethernet.
- Experience in high-speed transmitter and receiver circuit design.
- Knowledge of equalization techniques such as CTLE, DFE and FFE.
- Experience with PLL, CDR and clock generation circuits.
- Exposure to post-layout extraction and simulation.
- Understanding of signal integrity, jitter analysis and power optimization.

Education B.E./B.Tech/M.Tech in Electronics, Electrical Engineering, VLSI or a related discipline.
