Abstract
A cellular radio architecture that includes a receiver module having a receiver delta-sigma modulator that converts analog receive signals to a representative digital signal. The architecture further includes a transmitter module having a transmitter delta-sigma modulator for converting digital data bits to analog transmit signals. Portions of the receiver and transmitter modules are fabricated with silicon germanium (SiGe) technologies and portions of the receiver and transmitter modules are fabricated with CMOS technologies.
