  • Space efficient controllable switch type phase shifter
    Patent number: 11979128
    Abstract: Methods and apparatus for implementing a phase shifter in a space, e.g., chip surface area, efficient manner is described. In various embodiments a combination of switches, capacitors and a transformer are used in combination as a controllable phase shifter. In some embodiments the phase shifter supports a phase shift of 0 degrees or 180 degrees depending on the position of one or more switches. The mutual inductance of the transformer in at least some embodiments emulates one or more capacitors in a phase shift network making for an implementation that can be implemented on a semiconductor in an area efficient manner as compared to implementations using more capacitors and independent inductors.
