VLSI Research Intern - Vinod Dham Centre for Semiconductors (VDSemiX), New Delhi - New Delhi

(2025-06 - 2025-08)

• Designed and implemented a deep neural network hardware accelerator for MNIST, establishing a PyTorch-to-RTL hardware-software co-design pipeline.
• Deployed a custom parallel architecture using Q8.24 fixed-point arithmetic, mapping Multiply- Accumulate (MAC) operations to target DSP48E2 slices.
• Achieved >750x faster performance than a scalar CPU (intel core i5 processor) and ~9.1 us inference latency in simulation, preserving 97.8% accuracy through quantization and a custom RTL architecture.

• Implemented a Hybrid 3dB Coupler in Keysight ADS for 15-18 GHz operation using Rogers 4003C substrate.
• Achieved key specifications: Insertion Loss < 1 dB, Return Loss > 15 dB, and Isolation > 30 dB through microstrip layout tuning.
• Built full schematic and layout and validated power division and impedance matching through S-parameter analysis.
