  • A P-well GaAs MESFET technology

    Creator:
    Canfield, Philip C.
    Abstract:
    The semiconductor gallium arsenide (GaAs) has many potential advantages over the more widely used semiconductor silicon (Si). These include higher low field mobility, semi-insulating substrates, a direct band-gap, and greater radiation hardness. All these advantages offer distinct opportunities for implementation of new circuit functions or extension of the operating conditions...

  • A universal CMOS current-mode operational amplifier

    Creator:
    Botelho, Cindy
    Abstract:
    It has become customary in electrical engineering to think of signal processing in terms of voltage variables to the exclusion of current variables. This tendency has resulted in voltage signal processing circuits such as voltage-controlled voltage sources (VCVS) and voltage-mode operational amplifiers. However, the VCVS operational amplifier has several limitations...

  • Design of high-speed low-power analog CMOS decision feedback equalizers

    Creator:
    Su, Wenjun
    Abstract:
    Decision feedback equalizer (DFE) is an effective method to remove inter-symbol interference (ISI) from a disk-drive read channel. Analog IC implementations of DFE potentially offers higher speed, smaller die area, and lower power consumption when compared to their digital counterparts. Most of the available DFE equalizers were realized by using...

  • Energy-efficient OTA architectures using load-pole cancellation

    Creator:
    Ramakrishna, Pavan Kumar
    Abstract:
    The CMOS two-stage Operational Transconductance Amplifier (OTA) has been a key enabler for mixed-signal IC design for nearly four decades . This research focuses on a modified two-stage CMOS OTA that features load-pole cancellation (LPC); i.e., the resulting architecture is essentially a two-stage CMOS OTA with no load capacitance. The...

  • 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...

  • 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...

  • 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...

  • 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...

  • High accuracy CMOS switched-current ladder filters

    Creator:
    Hoei, Jung-sheng
    Abstract:
    Clock-feedthrough effects, channel-length modulation and device mismatch are the main causes of the inaccuracy of Switched-Current (SI) circuits. In this paper, these non-ideal effects are analyzed. A high-performance current mirror, namely regulated cascode current mirror, which eliminates drain voltage variation problem is introduced. By using this current mirror as a...

    Abstract:
    Advancements in the sophistication and complexity of modern electronic systems are creating a need for highly integrated systems with ever higher operational frequencies. The economical demands of these systems dictate that they be implemented using low cost fabrication technologies, such as digital CMOS. One of the major challenges facing circuit...
