A high-efficiency 27–30 GHz 0.13- ${{\mu } \text {m}}$ BiCMOS transmitter front end for mobile satellite communication (SATCOM) phased arrays is presented. A system-level analysis for determining the key parameters of the RF front end for the case

Next generation wireless devices will be required to support a wide variety of commercial standards and operate over a wide range of frequency bands. Two examples that are already receiving a lot of attention are software-defined and cognitive radios

This paper introduces a transformer-based, dual-coupled, triple-mode voltage-controlled oscillator (VCO) using a transformer-based fourth-order tank with tunable transconductance feedback between the primary and secondary coils. The tank impedance ca

This paper introduces a new phase noise analysis for one-port and two-port dual mode transformer-based (T-based) oscillators. In this paper we differentiate through linear time variant analysis between the noise response of L-based oscillators and du

This paper introduces a quadrature oscillator for LTE/LTE-A standards with an improved quadrature mode stability using transformers. In Inductor-based (L-based) quadrature voltage controlled oscillators (QVCO), there exist two stable quadrature modes

This paper studies how the reflected impedance impacts the quality factor and noise performance of transformer-based resonators. The analysis shows that in oscillators employing transformer-based resonators, the improved noise performance does not pr
