Two hierarchical levels have been considered for modulator simulation: idealized behavioral level and non-ideal circuit level. The program is written in MATLAB and allows the most relevant non-ideal parameters of the components to be taken into account. Among these parameters are limited switch resistances and gain-bandwidth product of active devices. Simulation of pattern and idle noises are considered as well.","PeriodicalId":375963,"journal":{"name":"Signals, Circuits and Systems, 2003. SCS 2003.

The main objectives with the approach are to significantly speed up the design process and to obtain better overall, possibly optimal, circuit performance compared to a manual, simulation-based, approach. In order to achieve good agreement with circuit simulators high accuracy transistor models are used. A key feature is the automatic generation of the performance metrics and cost function from the circuit netlist. As a design example we select a current-mirror operational transconductance amplifier.","PeriodicalId":375963,"journal":{"name":"Signals, Circuits and Systems, 2003. SCS 2003.

In this paper a new approach employing a current injection transistor to the output stage in order to inject the additional current needed for the large-signal settling in that interval and off in the remaining small-signal regime is presented. This technique decreases the power consumption in a fast-settling high-slew-rate operational amplifier driving a large capacitive load. Using this technique, a 1.8-V 3.3-mW op-amp driving a 4-pF load is designed with a 2Vp-p,diff 12-bit settling time of less than 11ns in a 0.35-μm CMOS process. HSPICE simulations confirm that this approach can reduce the power consumption by considerable amounts as high as 50%.","PeriodicalId":375963,"journal":{"name":"Signals, Circuits and Systems, 2003.

This fact makes the use of neural networks attractive for signal detection problems. In order to obtain good generalization excessive tuning is needed. Also, most of the neural network learning theories does not make use of the optimal hyperplane concept. In this paper, we consider optimal hyperplane signal detection with support vector machines (SVMs), for detecting a known signal corrupted by noise. Experimental results illustrate the detection performances in various cases. The practical implementation and the robustness of SVMs are also considered.","PeriodicalId":375963,"journal":{"name":"Signals, Circuits and Systems, 2003. SCS 2003.
