—A new injection-locked frequency divider (ILFD) circuit topology, by combining the strengths of LC type ILFD (LC_ILFD) and ring oscillator type ILFD (RO_ILFD), is proposed to achieve high speed, low power, wide locking range and accurate quadrature output phases. The frequency-division criterion is analyzed and agrees well with simulation results. The(More)
A compact 60GHz CMOS differential direct conversion receiver front-end based on eight-metal-layer interleaved on-chip transformers is realized for low voltage (1.2V) and high gain (24dB) operation with input 1dB compression point of-11dBm, Noise Figure of 10.5dB and power consumption of 4.3mW/arm. Compared with prior arts in CMOS, this receiver achieves the(More)
Deregulation of microRNAs (miRs) contributes to tumorigenesis. Down-regulation of miR-340 is observed in multiple types of cancers. However, the biological function of miR-340 in glioblastoma multiforme (GBM) remains largely unknown. In the present study, we demonstrated that expression of miR-340 was downregulated in both glioma cell lines and tissues.(More)
— Digital control of the effective dielectric constant of a differential mode transmission line is shown up to 60GHz in standard CMOS technology. The effective dielectric constant is shown to increase from 5 to over 50 for the fixed artificial dielectric case. The digital controlled artificial dielectric transmission line (DiCAD) uses MOS switches to(More)
