A novel ultra-high compliance, low power, very accurate and high output impedance current output stage (COS) with extremely high output current drive capability is proposed in this paper. The principle of operation of this unique structure is discussed, its most important formulas are derived and its outstanding performance is verified by HSPICE simulation in TSMC 0.18µm CMOS, BSIM3, and Level4...

the output of a piezoelectric nanogenerator based on zno nanowire is largely affected by the shape of nanowire. in order to obtain mechanically stable nanogenerator with high performance, the investigation of mechanical and electrical characteristics related to the nanowires and materials used in nanogenerators are of great interest and significance. this paper presents the various behavior of ...

This paper deals with concepts of output stability. Inspired in part by regulator theory, several variants are considered, which differ from each other in the requirements imposed upon transient behavior. The main results provide a comparison among the various notions, all of which specialize to input to state stability (iss) when the output equals the complete state.

In this work we discuss several notions on input-to-output stability for discrete time systems. We first discuss how the notions differ from each other, then we provide Lyapunov characterizations for these input-to-output stability properties. Copyright c ©2005 IFAC

Abstract. This paper deals with the stability analysis of fuzzy logic control (FLC) systems. The output characteristic of this class of controllers is nonlinear, thus it is necessary to use stability analysis methods for nonlinear systems. Here we use the Popov criterion. The systems analysed have a FLC with two input variables and one output variable, resulting in a surface as the nonlinear ou...

This paper is focused on the dynamic output feedback control of sampled-data system with actuator saturation using quantized measurements. The output signals are quantized before they are transmitted to dynamic output-feedback controller. An augmented system is constructed through a closed-loop system, which is a model with an interval time-varying delay and nonlinear items. Using discontinuous...
