  • A Fully Integrated Bio-potential Low-noise Amplifier Utilizing Capacitor Multipliers

    Creator:
    Yong, OnnLim
    Abstract:
    In any biomedical signal acquisition system, a front-end amplifier is needed to amplify low amplitude bio-signals while filtering out any unwanted low-frequency artifacts. The design of low frequency poles within the sub-Hz range implies very large time-constants which goes against system integrability. In recent years, the pseudo resistor has been...

  • Current-feedthrough cancellation technique for current-mode T/H circuits

    Creator:
    Young, David Y. W.
    Abstract:
    In this paper, an analysis of the clock-feedthrough effects in switched-current (SI)' circuits will be presented. The clock-feedthrough effects caused by the non-ideal characteristic of MOS switches when they are turned off limit the accuracy of the analog track-and-hold (T/H) circuits. A model to analyze and characterize this effect is...

  • A high-swing CMOS operational amplifier topology

    Creator:
    Yang, John Jian
    Abstract:
    A circuit topology for high-swing, high-linearity CMOS operational amplifiers has been developed. The technique uses parallel-connected p- and n-channel input pairs to realize an input common-mode voltage range nearly equal to the total power supply voltage. High linearity is achieved by summing the DC bias and AC small-signal currents so...

  • MOS switched-current biquadratic filters

    Creator:
    Lee, Bor
    Abstract:
    A MOS biquadratic (biquad) filter employing the switched-current technique is reported. The circuit uses current-mode processing which can offer wide bandwidth, low voltage operation, and can be implemented with standard CMOS technology. Examples of lowpass, highpass, and bandpass filters are given which illustrate the synthesis procedures and the versatility of...

  • Sensor Interface Circuit Design towards CMOS Scaling

    Creator:
    Liu, Jialin
    Abstract:
    Sensor system plays an important role in connecting everything including human body to the electrical information systems that we have built and that we are going to build, to make the world more intelligent and efficient. One of the key propulsive forces behind these emerging techniques is CMOS scaling that...

    Creator:
    Thota, Narayana Bhagirath
    Abstract:
    Deep Learning methods have been gaining a lot of significance for various Biomedical applications for diagnosing several types of diseases. Two applications considered here are: 1) Diabetic Retinopathy Detection and 2) ECG signal Classification (or Arrhythmia Detection). Diabetic Retinopathy (DR) is a major cause of blindness in Diabetic patients, and...

  • A high-swing class-AB CMOS operational amplifier

    Creator:
    Yu, Choung
    Abstract:
    A high-swing, high-linearity Class-AB CMOS operational amplifier suitable for high speed application is presented. It does not exhibit large-signal slewing effects as do others; its output current is limited by MOSFET aspect ratios and the total power supply voltage. A rail-to-rail common-mode input range is achieved by a topology which...

  • A chopper-stablized CMOS operational amplifier

    Creator:
    Ann, Seung-Han
    Abstract:
    The chopper-stabilized operational amplifier has good low frequency noise properties. Unfortunately a simple technique for simulation of the chopper-stabilized operational amplifier has not been available. This thesis describes the implementation of a differential amplifier using chopper stabilization and its circuit modeling for the SPICE simulation. This circuit has been designed...

  • Design of high-speed adaptive parallel multi-level decision feedback equalizer

    Creator:
    Xiang, Yihai
    Abstract:
    Multi-level decision feedback equalization (MDFE) is an effective technique to remove inter-symbol interference (ISI) from disk readback signals, which uses the simple architecture of decision feedback equalization. Parallelism which doubles the symbol rate can be realized by setting the first tap of the feedback filter to zero. A mixed-signal implementation...
