A Highly Sensitive Wide-Range Weak Current Detection Circuit For Implantable Glucose Monitoring |
Abstract | ||
|---|---|---|
A highly sensitive weak current detection circuit for implantable glucose monitoring is presented. The circuit consists of a current splitter, an integrator, a sampling/holding (S/H) circuit, and an 8-bit successive approximation register (SAR) analog-to-digital convertor (ADC). T-switches, source voltage shifting and correlated double sampling (CDS) technology are adopted to reduce the effects of leakage currents, charge injection, dc offset and low-frequency 1/f noise. The work range is divided into 5 sub-ranges to reduce the complexity and power consumption of current detection. The chip was fabricated with 0.13 mu m CMOS technology. Test results show that the circuit can detect weak signal from 10 fA to 1 nA with 1.5V supply and 7.2 mu W power consumption. The tested leakage current of the design is 4 fA. |
