This paper deals with the simulation of a Boost Power Factor Correction (PFC) Converter with Electro Magnetic Interference (EMI) Filter. The diode rectifier with output capacitor gives poor power factor. The Boost Converter of PFC Circuit is analyzed and then simulated with diode rectifier. The Boost PFC Converter with EMI Filter is simulated for resistive load. The power factor is improved usi...

This paper presents the design and fabrication of a feed horn antenna integrated fix-tuned 380GHz sub-harmonically pumped mixer, based on planar GaAs air-bridged Schottky anti-parallel diode from Rutherford Appleton Laboratory. The diode was designed and fabricated by millimeter technology group, Rutherford Appleton Laboratory, UK. The mixer’s circuit configuration and cavity block are realized...

Absfract—This paper describes and analyzes the circuits which have been used successfully for TRAPATT oscillator studies. The results lead to a better understanding of the TRAPATT oscillator and yield a simple model of the oscillator which is useful for circuit design. The circuit characteristics of ms experimental TRAPATT oscillator are determined from measurements on the circuits and from equ...

New diode structures without the field-oxide boundary across the p/n junction for ESD protection are proposed. A NMOS (PMOS) is especially inserted into the diode structure to form the NMOS-bounded (PMOS-bounded) diode, which is used to block the field oxide isolation across the p/n junction in the diode structure. The proposed N(P)MOSbounded diodes can provide more efficient ESD protection to ...

Power saving is more important than any other thing now a days because high speed and low power design continues to get more attention. In this paper, low power dynamic circuit [1] has been implemented at 180nm, 90nm, 45nm and 32nm technology, using HSPICE. The simulations are performed on CosmosScope. The power saved is up to 46%, 50%, 51% and 73% for 180nm, 90nm, 45nm and 32nm technology resp...

In general terms, it is not possible to establish symbolic explicit analytic expressions of the operating point and transient analysis for circuits containing diodes modelled using an exponential function. Therefore, this work propose replacing the diode for an equivalent circuit obtained by using a power series and a Taylor series consecutively. Finally, we present a symbolic solution for some...

The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips very high density, has recently led rapid and inventive progresses low-power design. most effective technique is adiabatic logic circuit design energy-efficient hardware. This paper presents two approaches for the low circuits, modified positive feedback (modified PFAL) other direct cu...

This paper considers three pairs of circuit schemes for RF rectification. Given finite available power from RF source and load resistance, we formulate DC output power and efficiency of each scheme. Resultant formulas find that load-to-source resistance ratio R/r dominates the circuit performance. Maximum efficiency reaches 81.1% at R/r = 1 for single-diode half wave rectifiers. It also reaches...
