One embodiment relates to a feedback receiver (FBR). The FBR includes a FBR signal input configured to receive a radio frequency (RF) signal, a first local oscillator (LO) signal input configured to receive a first LO signal having an LO frequency, and a second LO signal input configured to receive a second LO signal having the LO frequency. The second LO signal is phase shifted by approximately 90&#xb0; relative to the first LO signal. FBR also includes a divider that induces a time-varying phase shift in the first and second LO signals while concurrently retaining a 90&#xb0; phase shift between the first and second LO signals.
