title = "A 76μW, 58-dB SNDR analog front-end chip for implantable intraocular pressure detection",
abstract = "This paper proposes a low-power, high-performance and fully-integrated Analog Front-End (AFE) For implantable and real-time intraocular pressure (IOP) detection. It includes full-integrated, subthreshold amplifier and 10bit, 20ks/s low-power successive approximation analog-to-digital converter (SAR ADC). In amplifier pseudo-resistors are realized with subthreshold transistors to achieve G-order value. And it is also paralleled with feedback capacitor to generate high-pass path to restrict DC-offset voltage and low-frequency noise. Low-power SAR ADC is optimized to realize tradeoff between performance and power consumption. The AFE chip is implemented with 0.18 μm CMOS mixed-signal technology. By test results it shows that under 1.8V power supply, peak Signal-to-Noise and Distortion Ratio (SNDR) of AFE is 58.3dB and Effective Number of Bits (ENOB) reaches 9.4bit with only 76μW power consumption, which indicates great potential for IOP application.",
