| n the receiver of a digital communication system, the use of an analog-to-digital converter (ADC) allows many useful functions be implemented digitally. As the speeds of digital communication systems rise, so does the speed associated with the corresponding ADC. The quantization noise introduced by the ADC is dependent on the number of bits of the ADC and needs to be kept within system specifications. However, every additional bit added to a high-speed ADC complicates its design and increases its power, area and input capacitance. In this thesis, nonuniform quantization is investigated to try to lower the quantization noise introduced. An ADC employing variable nonuniform quantization has been implemented in a 0.5... |
