Abstract
A control unit has been proposed, which is used to reconfigure a pipeline ADC for a mobile terminal receiver that can drastically reduce the power dissipation dependent on adjacent channel interference. The proposed design automatically scales the word length by monitoring the quantization noise along the in-band and out-of-bands powers in the UTRA-TDD spectrum. The new ADC performance was evaluated in a simulation UTRA-TDD environment because of the large near far problem caused by adjacent channel interference from adjacent mobiles and base stations. Results show that by using the control unit to reconfigure the ADC, up to 88% power dissipation could be saved, when compared to a fixed 16 bits ADC without the use of the control unit. This will prolong talk and standby time in a moble terminal.
