Highly compact 3.1 - 10.6 GHz UWB LNA in SiGe HBT technology
Beitrag zu einer Konferenz
We present the design, implementation and measurement of a low noise amplifier (LNA) in a low cost 0.8 mym SiGe hetero-junction bipolar technology (HBT). The measured noise figure is between 2.1 dB and 2.6 dB in the ...
EMMA - a suggestion for an Embedded Multi-Precision Multiplier Array for FPGAs
Beitrag zu einer Konferenz
A non-monolithic top-down reconfigurable multiplier suitable for embedding in an FPGA structure called EMMA is presented. It is constructed of four individual partitions that can operate as separate multipliers but also ...

The gradient based nonlinear model predictive control software GRAMPC
Beitrag zu einer Konferenz
This paper presents the nonlinear model predictive control (MPC) software GRAMPC (GRAdient based MPC - [græmp si:]) which is suited for controlling nonlinear systems with input constraints in the (sub)millisecond range. ...
A parallelizable decomposition approach for constrained optimal control problems
Beitrag zu einer Konferenz
This paper describes a decomposition approach for the solution of constrained optimal control problems (OCPs) that is implementable in a parallel manner. A transformation method is applied to the constrained OCP by means ...
Model predictive control of an overhead crane using constraint substitution
Beitrag zu einer Konferenz
This paper describes a real-time model predictive control (MPC) scheme for an overhead crane subject to state and input constraints. The constraints are taken into account by means of a transformation technique which ...
A novel dual polarization antenna array fed by a dual mode non-radiative dielectric waveguide
Beitrag zu einer Konferenz
This paper presents the design and implementation of a dual polarization antenna with a low loss, planar feeding structure applicable for both, communication and radar applications at mm-wave frequencies. The array and ...
33 - 43 GHz and 66 - 86 GHz VCO with high output power in an 80 GHz fT SiGe HBT technology
Beitrag zu einer Konferenz
This letter presents a signal generation circuit that
combines a wide tuning range voltage controlled oscillator (VCO) and a frequency doubler. The VCO provides two differential outputs with different power levels. A ...
