This paper studies a chaotic spiking oscillator consisting of two capacitors, two voltage-controlled current sources of signum shape and one impulsive switch. The vector field of circuit equation is piecewise constant and embedded return map is piecewise linear. Using the map parameter condition for chaos generation is given. Using a simple test circuit typical phenomena can be confirmed experi...

Switched-capacitor (SC) circuits are analog discretetime signal processing circuits. At the front-end of these circuits, the continuous-time input signal has to be transformed into a discrete-time version. In order to optimize the settling speed of the SC circuit by creating step-input settling responses, the input interface circuit has to transform the continuous-time input signal into a unifo...

As the demand for fully integrated power management system has increased in recent years, the switched-capacitor (SC) converter has shown exceptional promise due to the favorable energy density of capacitors, but its limited output range and its intrinsic charge-sharing loss have limited its range of applications. In this paper, a resonant switched-capacitor (ResSC) topology is presented as a w...

Phased arrays in CMOS for consumer communication bands aim to enhance receiver performance by exploiting beamforming with antenna arrays. Sensitivity increases with the number of antenna elements through array gain and interferers can be cancelled through the spatial filtering of the beam pattern [1]. For the latter, the linearity of the receiver before the beamforming summing point becomes a b...

High sampling rate analog-to-digital converters (ADCs) are commonly used to sample complex modulated signals at intermediate frequencies in modern wireless receiver designs. Often CMOS switched-capacitor based ADCs are selected for such designs due to their attractive low cost and power dissipation. These ADCs utilize an unbuffered front end directly coupled to the sampling network, which prese...

High-efficiency Step-Up Converter by using PV system with Reduced Diode Stresses sharing is proposed in this paper. Through employ of coupled inductor and switched capacitor, the proposed converters attain high step-up conversion ratio without operating at extreme duty ratio. Due to reutilize of leakage energy, the efficiency is developed and the large voltage spike on switch is improved, This ...

This thesis project examines the design of a monolithic audio-band digital-to-analog (D/A) converter with the objective of achieving a high signal-to-noise ratio, low analog die area consumption, and low static power dissipation. Issues relating to system design, digital signal processing, sigma-delta modulation, D/A topology selection, and switched-capacitor filter design are covered. The Dire...

A switched-capacitor-based battery equalizer using level-shift circuits is proposed in this paper. In conventional equalizers using diode switches, the threshold voltage of diode switches causes a decrease in power efficiency. Unlike conventional equalizers, the proposed equalizer alleviates the threshold-voltage-drop of switches by using level-shift circuits. Therefore, the proposed equalizer ...

This paper deals with the simulation of fixed capacitor Thyristor switched Reactor Thyristor controlled reactor (FC-TSR-TCR) system. The FC-TSR-TCR system is simulated using MATLAB and the simulation results are presented. The power and control circuits are simulated. The current drawn by the FCTSR-TCR varies with the variation in the firing angle. Stepped variation of current can be obtained u...

This paper presents an analysis technique that can be used to compute the harmonic and intermodulation distortion levels of a sampled-data circuit directly from a SPICE transient analysis. It is useful for analyzing the non-linear behavior of switched-capacitor and switched-current circuits at the transistor level. The approach is valid for all input signal levels, makes no assumption of the un...
