Public boards
2-phase synchronous digitally controlled buck converter (30V in, up to 10A out). Features a 4-layer custom KiCad PCB optimized for EMI. Firmware written in C (HAL) for STM32G474, leveraging advanced hardware accelerators (HRTIM, FMAC) for dual-loop voltage/current control and LCD UI.
Custom 2-channel digital oscilloscope DAQ with 20MHz bandwidth. Built with a custom KiCad analog front-end (AFE) PCB, Gowin FPGA (Tang Nano 9K) for high-speed signal buffering (VHDL), and an RPi Pico MCU for SCPI-like control. Includes a simple Python GUI for data visualization.
2.4 GHz MIFA trace antenna design and simulation. Modeled using Ansys HFSS with Optimetrics sweeps to optimize geometry. Implemented on a custom 2-layer KiCad PCB using a coplanar waveguide. Includes LiteVNA verification diagnostics and a calculated Pi impedance matching network.
