APPARATUS AND METHOD FOR PHASE NOISE SELF-TEST

摘要

An integrated circuit (IC) having a radio receiver configured to perform a jitter self-test is disclosed. In one embodiment, an IC includes a radio receiver and a pulse generator. The pulse generator is configured to generate a pulse train based on a first periodic signal received from the radio receiver. The radio receiver is configured to use the pulse train to determine an amount of phase noise generated by a local oscillator of the radio receiver. The pulse generator and the radio receiver are implemented on the same IC die.
