01 — A little about me

Building at the intersection of circuits & computing.

RAHUL / 2026

I’m Rahul K Mahato, an Electronics & Communication Engineer and M.Tech candidate in Microelectronics & VLSI at IIT Roorkee.

My work sits at the intersection of digital design, transistor-level circuits, memory-centric computing and emerging non-volatile devices. I enjoy taking an architecture from a logic idea to a transistor-level implementation and simulation.

My current research focuses on FeFET-based compute-in-memory (CIM), including an 8×8 analog CIM array for 8-bit MAC operations, alongside SRAM-based Boolean in-memory computing.

The work investigates Compute-in-Memory as an alternative to data movement in conventional von Neumann systems. The core design is an 8×8 FeFET-based analog CIM array for 8-bit MAC operations, using a GlobalFoundries 28 nm HKMG process, Si:HfO₂ ferroelectric gate stack, PWM input encoding across four cycles and a hierarchical 1C-2C-4C capacitive shift-and-add network.

Additional work includes a Dual-Port 8T SRAM-based Boolean in-memory computing cell performing NAND, NOR, XOR and XNOR directly on SRAM bitlines. The designs are simulated in Cadence Virtuoso using BSIM + Verilog-A compact modeling.
