This paper presents a low-power, V-band doubler. A floating-Ground shielding transformer balun achieved a good balanced performance and input matching by using a central capacitor-based compensation technique. The doubler exhibits a 3-dB conversion gain (CG) bandwidth of 14 GHz range from 58 to 72 GHz and demonstrates a peak CG of −6.5 dB and peak efficiency of 7.7% with an output power of 0 dBm at...
In this paper, an analysis and calculation of the dc-link current and voltage ripples are presented for a three-phase inverter with unbalanced load. A comparison of the dc-link average and root-mean-square (rms) currents between considering and ignoring high frequency harmonics of the output current is drawn. It is shown that high frequency harmonic currents have little effect on the dc-link current,...
The characteristics of force transferring in parallel capacitor is presented, the external force applied on one plate can be transferred to another with a reverse direction and changed magnitude by coupling effect of mechanical domain and electric domain. The main principle of such behaviors is analyzed, and the relation of input and output is calculated by analytic method, it is indicated that the...
Dimension uncertainty inevitably occurs in almost every fabrication of microstructure because of its small size and ununiformity of material, therefore, the dimension error is a significant factor to be considered in MEMS structure design. The unsymmetrical gaps of capacitors induced by processing are selected to analyze the effects of error on the pull-in voltage of capacitive microaccelerometer...
