Low-Power Photoplethysmogram Acquisition Integrated Circuit with Robust Light Interference Compensation
To overcome light interference, including a large DC offset and ambient light variation, a robust photoplethysmogram (PPG) readout chip is fabricated using a 0.13-μm complementary metal-oxide-semiconductor (CMOS) process. Against the large DC offset, a saturation detection and current feedback circuit is proposed to compensate for an offset current of up to 30 μA. For robustness against optical...
متن کاملCircuit design for embedded memory in low-power integrated circuits
This thesis explores the challenges for integrating embedded static random access memory (SRAM) and non-volatile memory—based on ferroelectric capacitor technology—into low-power integrated circuits. First considered is the impact of process variation in deep-submicron technologies on SRAM, which must exhibit higher density and performance at increased levels of integration with every new semic...
متن کاملControl of Series Resonant Converter with Robust Performance Against Load and Power Circuit Components Uncertainties
Robust performance controller design for duty-cycle controlled series resonant converter (SRC) is proposed in this paper. The uncertainties of the converter are analyzed with load variation and power circuit components tolerances are taken into consideration. Additionally, a nominal performance (NP) controller is designed. Closed-loop system is simulated with Orcad and simulation results of r...
متن کاملLook up Table Based Low Power Analog Circuit Testing
In this paper, a method of low power analog testing is proposed. In spite of having Oscillation Based Built in Self-Test methodology (OBIST), a look up table based (LUT) low power testing approach has been proposed to find out the faulty circuit and also to sort out the particular fault location in the circuit. In this paper an operational amplifier, which is the basic building block in the ana...
متن کاملIntegrated Ambient Light Sensor with an LTPS Noise-Robust Circuit and a-Si Photodiodes for AMLCDs
Ambient light sensors have been used to reduce power consumption of Active Matrix Liquid Crystal Displays (AMLCD) adjusting display brightness depending on ambient illumination. Discrete sensors have been commonly used for this purpose. They make module design complex. Therefore it has been required to integrate the sensors on the display panels for solving the issue. So far, many kinds of inte...
