HIGH SPEED TRACKING DUAL DIRECTION CURRENT SENSE SYSTEM

摘要

A tracking current sense system is described that includes a first current tracking system, a second current tracking system, and a pre-biasing device. The first current tracking system is configured to replicate a first current flowing through a first switch and the second current tracking system is configured to replicate a second current flowing through a second switch. The pre-biasing device is configured to pre-bias the second current tracking system based on first information detected at the first current tracking system that is indicative of the first current and also, pre-bias the first current tracking system based on second information detected at the second current tracking system that is indicative of the second current.
