Abstract
A low noise RF driver circuit including at least two series-coupled driver stages which receive a frequency modulated signal and an amplitude modulated signal that is applied to the supply voltage input of the driver stages, and provide a combined output signal. The RF driver circuit can be implemented in CMOS technology and integrated with other components of an RF communication subsystem, such as an RF transceiver circuit and power amplifier. Each driver stage includes a complementary pair of transistors with source degeneration resistors for linearity and gain control.
