Fully integrated CMOS transmitter design considerations
نویسنده
چکیده
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 directconversion Tx uses digital control loop for nonlinearity corrections, CMOS technology can provide the route to a fully integrated Tx.
