Exponential stability and robust exponential stability relating to switched systems consisting of stable and unstable nonlinear subsystems are considered in this study. At each switching time instant, the impulsive increments which are nonlinear functions of the states are extended from switched linear systems to switched nonlinear systems. Using the(More)
A new novel fully-differential charge pump was designed in this paper, differential input and differential output was used in this circuit. The differential output circuit not only reduced the voltage noise created by leakage current, but also increased the ascending/descending speed and the range of output voltage. In the differential input, positive(More)
A novel structure of the integrated cascode crystal oscillator is presented by analyzing the discrete oscillator circuits in this paper. A temperature-independent voltage source, which is suitable for integrated circuits, was used for biasing of the buffer amplifier, while eliminating the bypass capacitor. Both the oscillator circuits and the buffer(More)
