摘要：An operational amplifier capable of compensating offset voltage includes aninput stage circuit having a positive input end, a negative input end, a first current outputend, and a second current output end, for outputting current corresponding to voltage
received by the positive and negative input ends, an output stage circuit coupled to thefirst current output end and the second current output end of the input stage circuit, foroutputting voltage according to current outputted from the first current output end andthe second current output end, and an trimming device coupled between the input stagecircuit and the output stage circuit, for adjusting current of the first current output endor the second current output end for compensating offset voltage.
