Temperature sensors identify hot programmable regions, then functions are relocated to cooler areas to avoid throttling and maintain data throughput.
Metastability detection and dual-delay logic keep pulse width constant across PVT variation without using clock signals that can leak secure information.
A ring oscillator detects PVT-driven output deviation, then DAC or PWM voltage adjustment stabilizes IC operation with low circuit complexity.
A voltage-feedback mechanism detects process, voltage, and temperature variations in semiconductor devices to adjust mirrored current references.
A noise filter circuit uses a decoupling unit and current amplifier to bypass transient disturbances on IC power pads.
