A 5-6 Ghz Silicon-Germanium Vco With Tunable Polyphase Outputs
In-phase and quadrature (I/Q) signal generation is often required in modern transceiver architectures, such as direct conversion or low-IF, either for vector modulation and demodulation, negative frequency recovery in direct conversion receivers, or image rejection. If imbalance between the I and Q …

… low-noise amplifier (LNA), a set of quadrature (I and Q)x~2 sub-harmonic mixers, and an LO conditioning chain. The front-end design provides a means to address performance limitations of the DCR architecture (such as DC-offsets, second-order distortion, and quadrature phase and …
