Embodiments of the invention may provide for a digital LINC (linear amplification with nonlinear components) transmitter. The digital LINC transmitter may include a signal component separator, at least one digital delay modulator, a frequency synthesizer, at least one power amplifier, a power combiner, an antenna, and a mismatch compensator. Additionally, systems and methods may be provided for compensating for phase and amplitude mismatches between two signal paths.

Embodiments of the invention may provide for an LC quadrature oscillator that includes two LC oscillators that are cross-coupled with each other to generate I/Q clock signals and a phase and amplitude mismatch compensator. The phase and amplitude mismatch detector may include an amplitude mismatch detector, a transconductor, and a capacitor for compensating for both phase and amplitude mismatches between I/Q clock signals generated in the LC quadrature oscillator.
