Abstract

Various embodiments of a radio-frequency (RF) transmitter receiver circuit that utilizes an injection locked oscillator may allow for the introduction of a DC offset to correct the RF signal. The DC offset may be adjusted to eliminate (or minimize) even order harmonics to correct for RF effects. The DC offset correction may be performed around the injection locked oscillator to target even order terms.
