Abstract:
In this paper some novel adaptor circuits are proposed to realize the unit element wave switched eapacitor filters driven by two phase clock signals. These circuits are very insensitive to the bottom plate parasitic capacitanees. To realize an adapto...

Abstract:
The incoporation and the behavior of impurity Cd in VPE of GaAs were studiecl using elemental Cd as a dopant in Ga-AsCl3-H2 system. The distribution coefficient of Cd and its solubility in GaAs were found to be 0.01-0.001 and 41018 cm-3 respectively....
