Abstract
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.
