  • A fast-settling folded-cascode CMOS operational amplifier

    Creator:
    Abu-Dayeh, Mahmoud A.
    Abstract:
    A fast-settling CMOS operational amplifier using the folded-cascode topology has been designed. The design is based on a theory developed by Yang et al for the optimum settling time of two-pole systems for switched-capacitor applications. The theory states that the two poles are separated by a given factor in order...

  • A CMOS differential line driver

    Creator:
    Jiang, William
    Abstract:
    A short-circuit-protected line-driver circuit is particularly adapted for use in a CMOS differential line-driver system, where one line-driver circuit provides a true output signal, and another line-driver circuit provides a complementary false output signal. A short-circuit is sensed by measuring current through a secondary pull-up transistor, and disabling a primary...

  • 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...

  • A photodetecting device that rejects ambient light

    Creator:
    Li, Ning
    Abstract:
    The integration of photodetectors with IC circuits provides a significant improvement over conventional designs. Featuring noise reduction, extended frequency responses, lower power consumption, and data operations, these integrated devices open challenging opportunities for many applications. One type of photodetector has the potential for important applications in the life science and...

  • 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...

  • 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 delta-sigma pulse width modulator with pulse dithering

    Creator:
    Lewison, Richard S.
    Abstract:
    Pulse Width Modulation (PWM) has been used extensively for motor control, DC-AC converters, DC-DC converters and in audio applications. The conventional method of generating a pulse width modulated signal involves generating an accurate sawtooth or triangle wave using analog circuits. In CMOS, being analog circuit intensive puts extra constraints on...

  • A CAD noise model for chopper-stabilized switched-capacitor filters

    Creator:
    Shenoy, Ravindra Umanath
    Abstract:
    A modeling technique for simulating the noise performance of chopper-stabilized switched-capacitor filters using SPICE2 is presented. A method for selection of switched-capacitor network (SCN) stages to be chopped and an op amp topology for low noise applications are also outlined. Validity of the modeling is verified by the close agreement...
