Abstract :
This paper presents a full-range broadband phase synthesis scheme with autonomous phase correction functionality. The on-chip phase measurement is achieved by a set of on-chip LO self-/inter-mixing testing sequences, which eliminates the need for auxiliary test tones. As a design example, a 2-to-6GHz quadrature phase synthesis system in a 65nm CMOS is demonstrated. The phase self-healing scheme achieves an RMS phase error of less than 0.6° and a full 360° interpolation within the entire band.
