  • Abstract
    A novel current-feedback operational amplifier, the input stage of which is based on the design and use in a repeated pattern of a current-transfer cell, exhibits performance characteristics superior to those obtained with an established input architecture: in particular, the common-mode rejection ratio (CMRR) is 105 dB, and the DC offset voltage less than 200 μV.
