This book provides readers with a single-source reference to current sensing integrated circuit design. It is written in handbook style, including systematic guidelines and implementation examples. The authors focus on the implementation of wide-bandwidth current sensing on a single microchip, toward usage in applications such as sensing, control and optimization of the energy flow in growth areas like industrial electronics, renewable energies, smart grids, electromobility and the Internet of Things.

Provides readers with a comprehensive, all-in-one source for current sensing integrated circuit design, including implementation examples;
Discusses modeling and optimization of on-chip Rogowski coil and Hall sensor in both lateral and vertical orientation;
Includes noise reduction techniques, such as auto-zeroing and chopping;
Covers open-loop and closed-loop sensor front-end design;
Presents the first on-chip current sensorwith a planar coil placed besides a power line to measure internal signal currents and the first off-chip current sensor with a helix-shaped coil for external signal currents in the multi-MHz region.
