A 25A Hybrid Magnetic Current Sensor with 64mA Resolution, 1.8MHz Bandwidth, and a Gain Drift Compensation Scheme

Autor: Jouyaeian, A., Fan, Q., Motz, Mario, Ausserlechner, Udo, Makinwa, K.A.A.

Publikováno v: 2021 IEEE International Solid-State Circuits Conference, ISSCC 2021-Digest of Technical Papers

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-
