A 6-bit active digital phase shifter
IEICE Electronics Express, 2011 This paper presents the design of a 6-bit active digital phase shifter in 0.18-µm CMOS technology. The active phase shifter synthesizes the required phase using a phase interpolation process by adding quadrature phased input signals. It uses a new quadrature all-pass filter for quadrature signaling with a wide bandwidth and low phase error.

A digital phase shifter with 7.5° resolution
Journal of Magnetic Resonance (1969), 1989 Abstract A high-resolution, digital, radiofrequency phase shifter which provides phase resolution of 7.5° in 48 steps under computer control is described. This phase shifter is constructed as an addition to an existing NMR instrument and is operated in parallel with the standard 90° resolution phase shifter. The addition requires no external signals,
