Product Overview

The agileIRDrop I-R Drop Sensor is a circuit to detect supply supply I-R drops within the system. It is useful to detect loss of power or attacks to the power supply.

The agileIRDrop consists of a voltage reference and comparator(s) set at different threshold levels for multi-level detection. The number of trigger outputs can be customized, and each threshold can be adjusted during operation to support DVFS operation. A four-output configuration is shown in the block diagram as reference.

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, Samsung Foundry and SMIC as well as other IC foundries and manufacturers.
