Abstract
Certain aspects of a method and system for RC-CR quadrature generation with wideband coverage and process compensation may include determining an amplitude mismatch between an in-phase (I) component and a quadrature (Q) component of a signal generated in a radio frequency (RF) transmitter or receiver. A variation in resistance of a quadrature network associated with the I component and Q component may be determined. The determined amplitude mismatch and the determined variation in the resistance of the quadrature network may be compensated by adjusting a resistance of a portion of the quadrature network associated with the I component and a resistance of a portion of the quadrature network associated with the Q component.
