A Low Power Discrete Time Band-Pass Sigma Delta Modulator ADC: Wireless LAN Receiver - Softcover

Inhaltsangabe

In recent telecommunication field, there are number of applications have been used such as cellular telephony, radio and television, medical imaging, high definition video processing, and multichannel applications. Nowadays sigma-delta modulator is one of the most popular architectures used in high-performance analog-to-digital and digital-to-analog converters, especially in high resolution and medium-to-low speed applications. Sigma-delta modulators are the most suitable analog to digital converter topologies for digitizing with high resolution analog signals at low frequency. Band pass sigma-delta modulators have recently received great consideration in the academia as well as in the industry. Today, there is a strong trend in using the band-pass (BP) sigma-delta ADC. The BP sigma-delta modulators allow for ADC in high IF and RF signal bands. As a result there is a large effort to develop and design high performance low power BP sigma-delta ADC for wireless mobile terminals. This book proposed design and experimental results of a 2nd order, discrete-time (DT), band-pass (BP) sigma delta modulator focused for wireless LAN receivers. In this book, 2nd order discrete time BP SD.
