    • A variable phase amplifier circuit is disclosed and its method of use in tuning devices having resonators. The variable phase amplifier receives an input differential signal pair. The input differential signal pair can be generated by a resonator device. The variable phase amplifier generates a modified differential signal pair in response to receiving the input differential signal pair. The variable phase amplifier provides a means to vary the phase of the modified differential signal pair with respect to the input differential signal pair, in an accurate and stable manner. If the modified differential signal pair with a phase shift introduced in it is fed back to the resonator device, the resonator will change its frequency of oscillation, where the new frequency of oscillation is a function of the phase of the modified differential signal pair.

    • Described herein is an apparatus, method and system corresponding to relate to a low power digital phase interpolator (PI). The apparatus comprises: a digital mixer unit to generate phase signals from a series of input signals, the phase signals having phases which are digitally controlled; a poly-phase filter, coupled to the digital mixer unit, to generate a filtered signal by reducing phase error in the phase signals; and an output buffer, coupled to the poly-phase filter, to generate an output signal by buffering the filtered signal. The low power digital PI consumes less power compared to traditional current-mode PIs operating on the same power supply levels because the digital PI is independent of any bias circuit which are needed for current mode PIs.

    • A stabilized quadrature RC/CR phase shifting network for generating quadrature RF and microwave signals. The network uses offset biasing of postamplifiers following the phaseshifter to fine tune quadrature-phase, and further uses an output quadrature-phase detector to stabilize quadrature-phase with negative feedback by using the quadrature-phase error signal to drive the quadrature-phase fine tuning control. In an alternative embodiment, the stability of quadrature-phase can be enhanced without the output quadrature-phase detector by making the quadrature-phase fine tuning control dependent upon the amplitude- difference negative feedback error signal.
