本书偏重于模拟电路方向，全面阐述以运算放大器和模拟集成电路为主要器件构成的电路原理、设计方法和实际应用。电路设计以实际器件为背景，对实现中的许多实际问题尤为关注。-The book is biased towards the direction of the analog circuit, a comprehensive exposition of circuit theory, constitute the main components of operational amplifiers and analog integrated circuit design methods and practical applications. Circuit design to the actual device is particularly concerned about the background, many practical problems in the implementation.
