Ultra-low power VLSI IP expert Omni Design has unveiled the ODT-PVT-ULP-001C-3, a new process, voltage, and temperature (PVT) monitor tailored for 3nm CMOS technology. Operating on a single 0.75V core-voltage supply, this ultra-low power IP simplifies integration while delivering unmatched precision for next-generation semiconductor chips, from data centers to autonomous systems.
Designed to function flawlessly across a temperature range of -40°C to 150°C, the ODT-PVT-ULP-001C-3 achieves ±4°C temperature accuracy without calibration and ±1°C after a single room-temperature trim. Its voltage monitor supports four differential or single-ended inputs, handling voltages up to ±0.75V, while a one-shot mode enables on-demand measurements, minimizing power use by entering a low-power standby state when idle. The process monitor provides clear digital insights into core and I/O PMOS and NMOS transistor variations, aiding design optimization.
As 3nm designs push thermal and power boundaries, Omni’s PVT monitor eliminates the need for complex guard bands, enabling dynamic voltage and frequency scaling (DVFS) to maximize performance. It supports real-time monitoring to mitigate silicon aging, enhance reliability, and counter side-channel security risks. The solution also collects thermal data to inform future designs, speeding time-to-market for advanced chips.
“Omni Design’s PVT monitor simplifies deployment in 3nm designs with a single core-voltage rail, unlocking significant power savings,” said Dr. Kush Gulati, President and CEO of Omni Design Technologies. “Saving just 1% power in data centers through our solution can translate to over $3M in annual operating cost reductions.”
Part of the OmniTRUST family, this compact, low-power monitor is customizable across multiple semiconductor foundries and process nodes. By enabling adaptive power management, thermal regulation, and predictive reliability, the ODT-PVT-ULP-001C-3 can help in designing AI and high performance chips lasting longer, work at optimal performance and also secure from side-channel security attacks.
