    • Calibrated Continuous-Time Sigma-Delta Modulators 
      Lu, Cho-Ying (2010-07-14)
      To provide more information mobility, many wireless communication systems such as WCDMA and EDGE in phone systems, bluetooth and WIMAX in communication networks have been recently developed. Recent efforts have been made ...
    • Design and fabrication of highly efficient electrooptic modulators using bragg grating reflectors 
      Kim, Ryoung-Han (Texas A&M University, 2006-04-12)
      Bragg grating reflectors etched in amorphous silicon overlay films have been integrated with Ti:LiNbO3 optical waveguides. With a 12.5 mm long grating segment and an etch depth of ~ 93 nm in a 105 nm-thick silicon film, a ...
    • An Open-Loop Amplifier Multi-Bit Sigma Delta Modulator 
      Miki, Takashi (2017-08-16)
      A new multi-bit quantizer for sigma delta modulators is proposed. The multi-bit quantizer has multiple single-bit quantizers, and the output of one of the single-bit quantizers is fed back to the input of another single-bit ...
    • A prototype of a new class of oversampling adc 
      He, Jun (Texas A&M University, 2006-08-16)
      Analog-to-digital (A/D) and digital-to-analog (D/A) converters are important blocks in signal processing system because they provide the link between the analog world and digital systems. Compared with Nyquist-rate data ...
