A 28 GHz SiGe QVCO and divider for an 81-86 GHz E-band beam steering transmitter PLL
This paper presents a QVCO and divider for a 28 GHz SiGe PLL. It was designed in a SiGe process with fT= 200 GHz. The PLL is intended to be used for beam steering in an 81-86 GHz E-band transmitter. Phase control is implemented by programmable current injection into the loop filter. The simulations in Spectre use a layout extracted view with parasitics for the QVCO and the frequency divider and an

A generic model for MIMO wireless propagation channels
We study the MIMO wireless channel, and derive a generic channel model that we believe has the ability to explain all important effects, including (i) interdependency of directions-of-arrival and directions-of-departure, (ii) large delay and angle dispersion by propagation via far clusters, (iii) rank reduction of the transfer function matrix. We point out the relevant propagation effects, and pro
