aSince the noise tone at the VCO supply is bandpass filtered by the PLL, the conventional design exhibits a bell-shaped curve. The curve is flattened by the VCO, indicating that the proposed VCO with on-chip calibration suppresses the supply noise for any supply modulation frequency. 因为PLL在...
characteristic of this contact is shown in FIG. 3. The total resistance of 1.4 ohms demonstrates the high potential of the present ohmic contact method. As indicated in FIG. 3 the current voltage characteristic exhibits strictly linear behavior with S- and N- shaped patterns absent on all ...
