Abstract: A phase shifter circuit may include a multiple phase shifter cells (or cells) to selectively shift a phase of an input signal by a desired phase shift value. For example, each of the phase shifter cells may shift the phase of the input signal by a positive fractional phase shift value or a negative fractional phase shift value. The phase shifter cells may include circuitry to form an inductor-capacitor circuit to provide the negative fractional phase shift value and form a capacitor-inductor circuit to provide the positive fractional phase shift value. The phase shifter cells may receive control signals to form the inductor-capacitor circuit and the capacitor-inductor circuit. An electronic device may include multiple phase shifter circuits to adjust a phase of transmission signals and/or reception signals of phased array antennas.
