Common mode filtering using feedthrough capacitors. A third approach to attenuate common mode current on a single conductor is to use an inductor, see Figure 7. An inductor in series acts like a short at DC and low frequencies. At high frequencies an inductor acts like an open. The voltage across an inductor is related to current by the rate of change in current. dt di V =−L

As is discussed above, this paper proposes a dual mode step-down SC DC-DC converter with four conversion ratios. PFM is adopted at heavy load while burst mode is adopted at light load. PFM achieves small output voltage ripple and high precision, a detailed system stability analysis is introduced.
In the burst mode, the VCO turns off and turns on intermittently to get a stable output voltage V OUT. The advantages of dual mode control strategy are achieved in the SC DC-DC converter. The converter gets smaller ripple, higher efficiency and faster load transient over the entire load current range.
The simulated Q and inductance of a capacitor-loaded (CL)and open-loaded (OL) transformer- based VID is shown in Fig. 3 where it can be seen that the Q of a CL-VID is directly related to the Q of the capacitor.
As an example, a 40fF capacitor with a Q equal to 50 results in Q of 25 for the VID at 65 GHz, while that drops to around 15 for the capacitor with Q of 10. As discussed earlier, varactors suffer from low-Q in mm-wave frequencies, and it is not a good choice for construction of high-Q VIDs.
Dual mode control is adopted in the SC DC-DC converter, the SC DC-DC converter works in PFM for heavy load condition while in burst mode for light load condition. In PFM, the EA (error amplifier) compares the V OUT with the reference voltage V REF.
This design proposes a novel dual mode control strategy to achieve high performance over a wide load range. PFM is adopted at heavy load to achieve the small output voltage ripple while burst mode is adopted at light load to improve transient response and power efficiency.
