A low-noise and low-area-consumption power management dedicated to CMOS pixel sensors for high energy physics experiments

摘要

The crosstalk between CMOS pixel sensors (CPS) degrades the performances of detector systems. Moreover, power distribution becomes a challenge in the future detectors for high energy physics experiments. In order to address these problems, a power management is proposed. Power supply voltages and reference voltages are internally generated in CPS. Two full on-chip linear regulators are proposed in this paper. Low area, low power consumption and low noise are achieved by a novel structure. The regulators have been designed and fabricated in a 0.35-μm commercial process. The measurement results are also presented.
