Fully integrated CMOS transmitter design considerations 

Nov 1, 2007, By Louis Fan Fei

Traditionally, multiple IC chips are needed to build transmitters (Tx) used in wireless communications. The difficulty with a full Tx integration is that each Tx building block uses different technology. A power-detection circuit will exploit the Schottky diode, while the modulator IC is integrated with BiCMOS or SiGe. Likewise, the digital control loop is implemented in CMOS. Now that direct-conversion Tx uses digital control loop for nonlinearity corrections, CMOS...
