PVT Sensor Subsystem

Overview

The agilePVT Sensor Subsystem is a low power integrated macro consisting of Process, Voltage, and Temperature sensors, and associated reference generator, for on-chip monitoring of a device's physical, environmental, and electrical characteristics. The monitoring of process, voltage and temperature variations are critical to optimize power and performance for modern SoCs/ASICs, especially for advanced node and FinFET processes.

Agile Analog designs are based on tried and tested architectures to ensure reliability and functionality. Our design methodology is programmatic, systematic and repeatable leading to analog IP that is more verifiable, more robust and more reliable. Our methodology also allows us to quickly re-target our IP to different process options. We support all the major foundries including TSMC, GlobalFoundries, Intel Foundry, Samsung Foundry, UMC and Other Foundries.
