This compact low-power Analog Front- End has been designed for wireless systems as the baseband part of the solution. The AFE consists of two ADC IQ pairs, two DAC IQ pairs, one auxiliary ADC and DAC and a clock generation block. This AFE would form the baseband part of a two chip solution. The AFE is intended for integration into a larger digital baseband chip and acts as the communication medium between the RF and digital blocks.
The design does not require any special analog options using the baseline digital CMOS process makes it ideal for integration with a DSP engine.
