It is composed of a magnetic-field-to-pulse width converter (MPC), a cyclic pulse-shrinking time-to-digital converter (TDC) and a polarity detector. This prototype circuit has been fabricated in a 0.5mm CMOS DPDM process. With a clock rate of 16.6 kHz, the power consumption is 42.5mW under 5V supply voltage. The equivalent resolution less than 16mT can be achieved within the range of 710mT. After off-line calibration, the remaining offset is 0.017mT and its gain error is smaller than 0.4%.application/pdf652593 bytesapplication/pdfzh-TWdynamic stabilityshallow archenergy barrierend motionElectric potential; Energy utilization; Error analysis; Gain measurement; Magnetic fields; Networks (circuits); Magnetic field-to-digital converters; Magnetic-field-to-pulse width converter (MPC); Supply voltage; Time-to-digital converter (TDC); Pulse width modulationjournal article10.1049/ip-cds:200451682-s2.0-33745348389http://ntur.lib.ntu.edu.tw/bitstream/246246/200611150121282/1/559.pdf
