Abstract :
Active current-mode compensation is used to minimize the undesirable effects of the capacitive embedding on the performance of switched-capacitor integrators. This is shown to lead to significant reductions in amplifier power consumption and chip area. In addition, the compensation reduces the degree of interaction between amplifiers during the various clock phases, thus improving filter response accuracy
