摘要
Popular methods for reducing the input offset voltage of comparators and amplifiers are reviewed. A comparator that adjusts its own offset either at power-up or in response to a control input is presented. The nature of the offset adjustment is such that the comparator is capable of continuous-time operation. Room-temperature offsets in the range of -100 to +100-mu-V are achievable. Adjusted offsets exhibit a temperature coefficient on the order of -1-mu-V/degrees-C.
