Hardware-Aware Spectrum Monitor

ISM band channel occupancy analyzer with jammer-like anomaly detection — CMOS role

Passive, hardware-aware spectrum sensing platform for real-time channel occupancy analysis and interference detection in the 865–867 MHz ISM band using LoRa, FPGA, and CMOS.

  • Designed a transistor-level StrongARM latch comparator in Xschem/Ngspice achieving 6–7 mV sensitivity and 10 ns decision time under low-amplitude, noise-dominated inputs
  • Performed end-to-end validation across noise-only, signal-present, and jammer conditions, demonstrating correct channel occupancy detection and dual-threshold interference classification
  • Analyzed metastability as a functional indicator, detection margins, and transition dynamics between uncertain and deterministic decision regions
