High boost DC/DC voltage conversion is always indispensable in a power electronic interface of certain battery-powered electrical equipment. However, a conventional boost converter works for a wide duty cycle for such high voltage gain, which increases power consumption and has low reliability problems. In order to solve this issue, a new battery-powered combined boost converter with an interle...

In this paper, a high-conversion-ratio bidirectional dc–dc converter with coupled inductor is proposed. In the boost mode, two capacitors are parallel charged and series discharged by the coupled inductor. Thus, high step-up voltage gain can be achieved with an appropriate duty ratio. The voltage stress on the main switch is reduced by a passive clamp circuit. Therefore, the low resistance RDS(...

In this paper, a novel high step-up DC-DC converter is proposed for sustainable energy system. The proposed converter uses coupled inductor and switched-capacitor technique. The capacitors are charged in parallel and are discharged in series by the coupled-inductor to achieve high stepup voltage gain with appropriate duty ratio. Besides, the voltage stress on the main switch are reduced with a ...

Abstract: A 1 V operating fully differential OTA is presented. We designed a 1 V operating fully differential OTA using NMOS inverters in place of traditional differential pair. To obtain high voltage gain, a two stage configuration has been used in which the first stage has feedforward to cancel common-mode signal and the second stage has commonmode feedback. This OTA was fabricated by 0.18 μm...

Current Feedback Amplifiers (CFA) are discussed in this report. Current Feedback Amplifiers employ the current mode of signal processing to achieve higher gain-bandwidth product and greater slew rates than those of a Voltage Feedback Amplifier (VFA). The Current Feedback Amplifier topology has an inherent advantage over that of the the Voltage Feedback Amplifier, wherein the amplifier gain can ...
