—We study the performance of compressed beamforming weights feedback technique in generalized triangular decomposition (GTD) based MIMO system. GTD is a beamforming technique that enjoys QoS flexibility. The technique, however, will perform at its optimum only when the full knowledge of channel state information (CSI) is available at the transmitter. This(More)
This paper presents a pulse generator (PG), aiming at low power applications with low duty cycle. The PG is capable to provide an efficient pulse generation at a frequency near and beyond CMOS's Fmax. It also features quick starting time and zero stand-by power. The PG is designed by CMOS flipped to a transmission line resonator on a quartz substrate.(More)
A pulse generator (PG) for low power and low duty cycle applications is presented. The PG employs a CMOS switch and a quarter-wavelength transmission line resonator. Since the architecture does not involve feedback gain, the PG is theoretically capable to generate a pulse efficiently at high oscillation frequency (f<inf>osc</inf>), at which a transistor(More)
