a log-domain current-mode true rms-to-dc converter based on a novel synthesis of a simplified current-mode low pass filter and a two-quadrant squarer/divider is presented. the circuit employs floating gate mos (fg-mos) transistors operating in weak inversion region. the converter features low power(<1.5uw), low supply voltage (0.9v), two quadrant input current, immunity from body effect, low ci...

We show that a finite Josephson Junction (JJ) chain, ending with two bulk superconductors, and with a weak link at its center, may be regarded as a condensed matter realization of a two-boundary Sine-Gordon model. Computing the partition function yields a remarkable analytic expression for the DC Josephson current as a function of the phase difference across the chain. We show that, in a suitab...

This paper proposes a minimal switching multiple input multilevel output (MS-MIMLO) DC-DC converter. Minimizing the cost of operation is an utmost priority any electric circuit design. Thus, reduction number switches that control and manage feeding power into MIMLO convertors presented. The proposed MS-MIMLO converter exerts many advantages, include high voltage transfer ratio with small size i...

In this project a new integrated multi level AC-DC converter is proposed. The proposed converter has two independent controllers. First controller is used to control the input side and the second for the output side. The input controller prevents DC bus voltage from becoming excessive and performs power factor correction and regulates DC bus voltage. The output controller regulates output volta...

An improved RF–dc converter based on a class-E rectifier with wide-dynamic-range input matching is presented. The input impedance is controlled by two varactor diodes to compensate for impedance changes with RF input power and dc loading conditions. The RF–dc converter achieved a peak efficiency of 60% and an S11 less than −20 dB over an input RF power range of 12 dB and an operating battery vo...

Boost half bridge DC-DC converters in the combination of an input-series and output-series (ISOS) connected configuration with a stable control strategy has been investigated in this paper. A stable control strategy comprises of two loops that are current loop and voltage loop. The reference to the current loop has been chosen from the input side of the DC-DC converter. The reference to the vol...
