Profile
An analog designer with a strong grip on fundamentals and a proven record of successful tape-outs and testing — at home anywhere between 112 Gbps FinFET equalisers and ultra-low-power ΔΣ converters.
- Analog/mixed-signal designer with a strong understanding of analog fundamentals and a proven track record of successful tape-outs and testing.
- Expertise in BiCMOS, deep-submicron CMOS and FinFET technologies, including 3nm, 5nm, 12nm, and 22nm nodes.
- Proficient with industry-standard EDA tools: Cadence Virtuoso, Synopsys Custom Compiler and HSPICE, Siemens Calibre, Cadence Pegasus, and Quantus.
- Experienced in high-speed equalization circuits (CTLE, FFE) and power-management blocks (LDO, bandgap).
- Hands-on with EM/IR (Voltus-Fi), automation (Python, Verilog-A), and multi-corner verification methodologies.

Analog Design Engineer at Neuron IP
- SerDes
- Low-Power Strong-Arm LatchDesigned for 32Gbps-XSR-NRZ UCIe standard.
- Porting of Strong-Arm LatchThe optimized design was ported to a more advanced node improving power consumption by 40% while keeping other parameters the same (Clk-to-Q, sensitivity, hysteresis, aperture time, …).
- LDODesign and verification of several LDOs with various requirements (low-noise, ultra-low headroom, high PSRR (<−15dB using a PMOS pass-device)).
- FFE for a 56GHz Optical Transmitter
- Clock DistributionDesign and verification of clock generator and distribution with rail-to-rail signals across all corners and less than 2.5% duty cycle error without a DCC.
- Current SummerDesign and optimization of multi-phase current integrating summer.
- Verification Methodology ImprovementCreated a Python-driven framework to automate testbench generation, simulation, and result visualization for analog IPs (LDOs, bandgaps, sense amplifiers) in HSPICE. The tool streamlined netlist integration, pin mapping, and multi-corner analysis, producing performance plots (e.g., PSRR, sensitivity) and tables automatically, achieving an order-of-magnitude reduction in verification effort.
- High Speed CTLEThis design is optimized for 112 Gbps in FinFET technology.
