It is well known that transmit power control is an essential component of any CDMA system. In conventional cellular systems, the interface between the wired network and wireless medium is the base station antenna (or closely located antennas if there is microdiversity) placed at the geographic center of the cell area. With such a " centralized " antenna,(More)
We present a fully implicit, monolithic finite element solution scheme to efficiently solve the governing set of differential algebraic equations of incompressible poro-elastodynamics. Thereby, we proceed from a two-dimensional, biphasic, saturated porous medium model with intrinsically coupled and incompressible solid and fluid constituents. Our approach,(More)
SUMMARY This paper presents a new efficient monolithic finite element solution scheme to treat the set of PDEs governing a two-dimensional, biphasic, saturated TPM model with intrinsically coupled and incompressible solid and fluid constituents for infinitesimal and large elastic deformation. Our approach, which inherits some of its techniques from CFD, is(More)
A low current front-end transimpedance amplifier (TIA) circuit for a high-speed light emitting diode (LED) and photodetector (PD) pair is presented. It mitigates PD capacitance effects by using a low input impedance buffer between the PD and the amplifier's input stage. Our simulation results show that a bandwidth in excess of 100 MHz can be reached for PD(More)
