Current Sense Amplifiers

the long version

This book provides a systematic and comprehensive insight into current sensing techniques. In addition to describing theoretical and practical aspects of current sensing, the author derives practical design guidelines for achieving an optimal performance through a systematic analysis of different circuit principles. Voltage sense amplifiers are also considered, since they are used as a final comparator in a current sense amplifier. Innovative concepts, such as compensation of the bitline multiplexer and auto-power-down, are elucidated. Although the focus is on embedded static random access memory (SRAM), the material presented applies to any current-providing memory type, e.g. also to emerging memory technologies such as MRAM. The book will appeal to design engineers in industry and also to researchers wishing to learn about, and apply, current sensing techniques.
