Code-Division Multiple Access, a digital Cellular technology that uses spread-spectrum techniques such as GSM, that use TDMA, but CDMA does not assign a specific frequency to each user. Wideband Code-Division Multiple Access (WCDMA), for the implementation of the Third-Generation (3G) cellular system. WCDMA efficiently utilizes the radio spectrum to provide a maximum data rate of 2 Mbit/s. As power is defined as the rate of energy transfer. Energy to dissipate away from the conductor into the surrounding, through the process of heat transfer. This paper based on Low power multimode switched capacitor sigma delta-modulator, A low power multi-rate 2-2 cascade sigma-delta modulator for Bluetooth, GSM, GPS, WCDMA, WLAN and WiMAX modes is proposed.
