Jouyaeian, A. (author), Fan, Q. (author), Motz, Mario (author), Ausserlechner, Udo (author), Makinwa, K.A.A. (author)Magnetic current sensors are used in switched-mode power supplies and motor drivers, where both galvanic isolation and wide bandwidth (BW) are desired. In CMOS, Hall-effect sensors are widely used, but their resistance results in a fundamental trade-off between BW and resolution. Coils have a differentiating characteristic and so can achieve...conference paper 2021
