Abstract
Disclosed is a four-phase generation circuit, comprising a pair of input ports configured to receive a differential signal having a common mode voltage; a polyphase filter having a pair of polyphase filter input ports and first, second, third and fourth output ports; a first circuit configured to provide the differential signal with an adjusted common mode voltage to the pair of polyphase filter input ports; wherein the first, second third and fourth output ports are each configured to output a square-wave signal, with 90° phase separation between consecutive output signals; and a feedback circuit from the first, second, third and fourth outputs ports to the first circuit; wherein the feedback circuit is configured to provide a feedback signal to the first circuit to set the adjusted common mode voltage from the common mode voltage.
