  • 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...

  • 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...

  • Power amplifier design in digital CMOS processes

    Creator:
    Forejt, Brett E.
    Abstract:
    The ability to integrate designs from board level, multi-chip modules to single process solutions is highly attractive in today's PC multimedia industry. Saving board area and chip count will decrease the production cost of personal computing hardware and increase profitability. The ability to integrate analog circuit capability and it's reference...

  • Operational amplifier compensation using doublet-decompression for switched-capacitor circuits

    Creator:
    Jen, Shin D.
    Abstract:
    A frequency compensation technique for increasing the settling speed of two-stage operational amplifiers used in switched-capacitor applications has been developed. By properly decompressing the pole-zero doublet to form a three-pole one zero system, the settling speed is increased up to 50 percent as compared to the optimized two-pole system.

  • 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...

  • Modeling of subthreshold current of GaAs MESFET and the design of voltage reference circuit

    Creator:
    Or, Pee-Keong
    Abstract:
    The characteristic of the subthreshold current in a GaAs MESFET exhibits a negative exponential function with Vgs. After studying the behavior of this current in this region over a range of temperature and drain bias voltages, a subthreshold current model was developed. The model was implemented in a circuit simulation...

  • Low-voltage Tracking RC Compensated OTA and a Rail-to-Rail Input and Output Operational Amplifier

    Creator:
    Kuo, Yu-Wen
    Abstract:
    The operational transconductance amplifier (OTA) is a fundamental building block in analog and mixed-signal systems. This research describes a process-, voltage-, and temperature- (PVT) insensitive low-voltage tracking RC compensation scheme considered for two-stage CMOS OTAs, which cancels the pole due to the load capacitance using a Miller zero generated by...

  • High speed analog circuit design using the heterostructure insulated gate field effect transistor

    Creator:
    Smith, Alexander B.
    Abstract:
    As Si MOS approaches its maximum limits in speed and bandwidth, new devices are desired to meet the needs of high speed communications and signal processing. A device that exhibits superior performance to Si MOS, BJT, and GaAs technology is the HEMT (high electron mobility transistor). The HEMT offers superior...
