(TU Delft Microelectronics) Department Microelectronics Date 2017 Abstract This paper proposes a multipath multisensor architecture for CMOS magnetic sensors, which effectively extends their bandwidth without compromising either their offset or resolution. Two designs utilizing the proposed architecture were fabricated in a 0.18-μm standard CMOS process. In the first, the combination of spinning-current Hall sensors and nonspun Hall sensors achieves an offset of 40 μT and a resolution of 272 μTrms in a bandwidth of 400 kHz, which is 40 times more than previous low-offset CMOS Hall sensors. In the second, the combination of spinning-current Hall sensors and pickup coils achieves the same offset, with a resolution of 210 μTrms in a further extended bandwidth of 3 MHz, which is the widest bandwidth ever reported for a CMOS magnetic sensor.
