Abstract :
An improved fully-balanced current-mode integrator structure is presented. The proposed structure improves the low frequency CMRR of integrators reported in the literature from the order of gm/g o to gm2/go2. Moreover, the new structure provides more flexibility to guarantee stability and is less sensitive to process mismatch. Several integrator topologies are compared. The differential and common-mode gains and the CMRR at low and high frequencies are analyzed
