  • 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...

  • CMOS analog design using a digital gate array

    Creator:
    Liu, Tian-chen
    Abstract:
    The core area of a conventional CMOS digital gate array consists of only one size of NMOS device and one size of PMOS device. Both primitives have fixed minimum channel lengths, and this has significantly impeded analog applications. This work has shown that by forming series and parallel interconnections between...

  • Design and computer aided optimization of a fully integrated CMOS RF distributed amplifier

    Creator:
    Ballweber, Brian M.
    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...

  • 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...

  • CMOS low noise amplifier design utilizing monolithic transformers

    Creator:
    Zhou, Jianjun J.
    Abstract:
    Full integration of CMOS low noise amplifiers (LNA) presents a challenge for low cost CMOS receiver systems. A critical problem faced in the design of an RF CMOS LNA is the inaccurate high-frequency noise model of the MOSFET implemented in circuit simulators such as SPICE. Silicon-based monolithic inductors are another...

  • Switch-capacitor Power Amplifier with Enhanced Power Back-off Efficiency and Linearity

    Creator:
    Qiao, Bo
    Abstract:
    Nowadays, wireless communication systems use high-order quadrature amplitude modulation (QAM) together with orthogonal frequency-division multiplexing (OFDM) to increase the link capacity and robustness. These signals always have large peak-to-average power ratio (PAPR) and require power amplifiers (PAs) achieve both high efficiency and linearity simultaneously. For the efficiency, the complementary metal...

  • 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...
