Wide-bandwidth lossless current sensors are critical in numerous applications, from current monitoring in DC-DC converters to non-invasive load monitoring. CMOS Hall sensor is a low-cost solution for current sensing and can be easily integrated as part of mixed-signal system-on-chips (SoCs). State-of-the-art CMOS Hall sensors offer only limited acquisition bandwidths of a few hundred kHz. This paper presents a 1 MHz Hall current sensor SoC integrating a broadband CMOS Hall sensor, two 2 MS/s ADCs and a multi-mode digital compressive sensing encoder for data rate reduction. The complete SoC is implemented in a STM 0.16 μm BCD technology, and occupies 16 mm2 while consuming less than 94 mW at 1.8 V.

Abstract
Wide-bandwidth lossless current sensors are critical in numerous applications, from current monitoring in DC-DC converters to non-invasive load monitoring. CMOS Hall sensor is a low-cost solution for current sensing and can be easily integrated as part of mixed-signal system-on-chips (SoCs). State-of-the-art CMOS Hall sensors offer only limited acquisition bandwidths of a few hundred kHz. This paper presents a 1 MHz Hall current sensor SoC integrating a broadband CMOS Hall sensor, two 2 MS/s ADCs and a multi-mode digital compressive sensing encoder for data rate reduction. The complete SoC is implemented in a STM 0.16 μm BCD technology, and occupies 16 mm2 while consuming less than 94 mW at 1.8 V.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
