A 10-bit Current-Steering DAC for Urinary Bladder Volume Measurement

A 10-bit Current-Steering digital-to-analog converter (DAC) is proposed to measure a urinary bladder volume. The proposed DAC is composed of a 4-bit pull current DAC, a 4-bit push-pull current DAC, and a 2-bit push-pull current DAC. Since output voltage range of three DACs is limited for the urinary bladder volume measurement, the resolution and power consumption of DAC are reduced. The proposed DAC is fabricated by phenitec
$0.6\mu \mathrm{m}$
1P3M CMOS process.
