    • 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.
