A CMOS implementation of a high-gain current mode operational amplifier (opamp) with a single-ended input and a differential output is described. This configuration is the current mode counterpart of the traditional voltage mode opamp. In order to exploit the inherent potential for high speed, low voltage operation normally associated with current mode analog signal processing, the opamp has be...

This paper presents implementations of a nonisolated, high voltage gain DC-DC converter. High voltage gain is achieved due to inclusion of resonance and transformer in the circuit. The performance of this converter is compared with two similar topologies namely coupled inductor-switched capacitor step-up converter and coupled inductor step-up converter. The proposed prototype is designed using ...

Voltage lift is a well-known technique to improve the voltage gain of converter. A combination switched inductor and conventional can be used achieve high gain, but semiconductor's stress still high. An improved by employing an extra diode capacitor proposed, which significantly increases boosting factor reduces semiconductor devices. The proposed converter transformerless non-isolated in natur...

Modulating the gain of the input-output function of neurons is critical for processing of stimuli and network dynamics. Previous gain control mechanisms have suggested that voltage fluctuations play a key role in determining neuronal gain in vivo. Here we show that, under increased membrane conductance, voltage fluctuations restore Na(+) current and reduce spike frequency adaptation in rat hipp...
