equivalent configuration
1.The Method of DecompositionDeduction for Deducing AtomicSpectroscopic Terms in jj Coupling of Equivalent Configuration
3.The two circuit techniques of equivalent inductance and cross-coupled configuration are used to design a high frequency,low phase noise two-stage VCO,which can generate two pair quadrature outputs because of its even stage ring.
4.Using SiGe BiCMOS darlington configuration as the input stage, the input resistance is increased by the MOS devices while the transconductance of SiGe HBTs is maintained. In the same time, the equivalent input noise is controlled well because of the SiGe HBTs’good noise performance in the input stage.
