  • Linearizing techniques for voltage controlled oscillator based analog to digital converters

    Creator:
    Rao, Sachin B.
    Abstract:
    Voltage controlled oscillator (VCO) based ADC is an important class of time-domain ADC that has gained widespread acceptance due to their several desirable properties. VCO-based ADCs behave like an open-loop continuous time ΔΣ modulator and achieve excellent resolution by first order noise shaping the quantization error. However, the SNDR of...

  • Highly digital power efficient techniques for serial links

    Creator:
    Inti, Rajesh
    Abstract:
    Low power, high speed serial transceivers are employed in a wide range of applications ranging from chip-to-chip, backplane, and optical interconnects. Apart from being capable of handling a wide range of data rates, the transceivers should have low power consumption (mW/Gbps) and be fully integrated. This work discusses enabling techniques...

  • Design techniques for high efficiency high current LED drivers

    Creator:
    Rao, Sachin B.
    Abstract:
    Solid-state based lighting offers a number of advantages such as long life, high efficiency and compactness compared to a conventional halogen tube based lighting. Due to these advantages they are being increasingly used in a variety of lighting applications including portable devices, home, and automotive lighting. Consequently, there has been...

  • An efficient frequency controlled PFM for DC-DC converters

    Creator:
    Pai, Jeff
    Abstract:
    As more features are being integrated into mobile platforms, the demand for long battery life during standby mode has been increasing. Light load efficiency becomes one of essential features in today's DC-DC converter. The most effective method to improve light load efficiency is to operate the DC-DC converter under pulse-frequency-modulation...
