A multiple-circuit high pulse repetition frequency (PRF) pulse generator for the pumping of rare gas halide lasers is reported. With this multiple-circuit design, high PRF can be achieved by the use of existing low PRF thyratron switches and capacitors. A two-circuit pulse generator was constructed, and its performance is described. By means of this pulse generator and a blowdown-type fast tran...

This article presents a new circuit to generate a higherorder derivative Gaussian pulse for the impulse radio ultra-wideband (IR-UWB) communication systems. This IR-UWB pulse generator is designed and measured with the TSMC 0.18m CMOS process. The circuit is able to generate a symmetrical and low-ringing pulse in a frequency band from 3.1 to 10.6 GHz. Our work shows that the pulse generator’s o...

This paper presents a simple nonautonomous circuit with a periodic pulse-train input. If the input does not exist, the circuit exhibits either equilibrium attractor or hard oscillation. If a periodic pulse-train input is applied, the circuit exhibits interesting chaotic and periodic attractors. The circuit behavior can be analyzed by a mapping procedure based on a 1-D return map focusing on the...

This paper studies a simple nonautonomous circuit consisting of an RLC resonator, a dependent switch and a periodic pulse-train input. The circuit can exhibit chaotic behavior if an equidistant pulse-train input is applied. The dynamics can be analyzed by a mapping procedure based on a one-dimensional (1-D) return map focusing on the moments when the input is applied. If the periodic pulse-trai...

A pulse-coupled neuron (PCN) circuit is proposed. This circuit uses a positive feedback circuit with two capacitors. One corresponds to the sodium ion potential and the other corresponds to the potassium ion potential and can be easily implemented in CMOS technology. The circuit behaves like a real neuron, generating a pulse train in which the frequency increases with an increase of input excit...

This paper presents a novel three-phase utility frequency to high frequency soft switching power conversion circuit with dual mode pulse width modulation and pulse density modulation for high power induction heating applications as melting of steel and non ferrous metals, annealing of metals, surface hardening of steel and cast iron work pieces and hot water producers, steamers and super heated...

A novel nonautonomous chaotic oscillator based on the passive structure of Chua's circuit is proposed. Unlike most of the available members of this class of chaotic oscillators, the proposed circuit is driven by a periodic bipolar pulse-train rather than by sinusoidal excitation. This results in equilibrium points which have ®xed positions in space. The circuit employs self feedback via a singl...

A duty cycle control circuit for clock signals is presented. The proposed circuit uses a rising edge detector to generate one shot output signals which have the same frequency of the input clock signal. A pulse width controllable monostable multivibrator converts the one shot signals into rectangular pulses. By the feedback control voltage from an operational amplifier, the pulse width of gener...
