| Abstract: | A high CMRR fully-balanced current-mode integrator structure is presented. The proposed structure improves the CMRR at low frequencies by a factor of gm/go. Moreover, the structure provides more flexibility to guarantee stability and is significantly less sensitive to process mismatches. The differential and common-mode gains and CMRR at low and high frequencies are analysed as well as verified in simulation |
