A half-bridge-based impedance-source inverter with two T-shaped coupled inductors is proposed in this article. Unlike the conventional half-bridge structure, topology can generate a zero-voltage level at its output stage. First, configuration and modulation method are described, which will analyze topology's various operational modes. Second, boost factor determined, way to design necessary pas...

A highly linear, low voltage, low power, low noise amplifier (LNA) using a novel nonlinearity cancellation technique is presented in this paper. Parallel Inductor (PI) matching is used to increase LNA gain by 3 dB at the desired frequency. The linear LNA was designed and simulated in a TSMC 0.18μm CMOS process at 5GHz frequency. By employing the proposed technique, the IIP3 is improved by 12 dB...

An analytical study of the effect of neutral base recombination on various transistor performance characteristics is presented. Using an approximate life time model which is suitable for BJT’s, pseudo-HBYs, and HBT’s with small variations in bandgap, closed form analytical relations for common emitter current gain, Early voltage and base and emitter delay times are derived including the effect ...

Compact low-voltage power-efficient operational amplifiers are described that are very suitable as very-largescale-integration library cells because of the small die area of 0.08 mm and the minimum supply voltage of 1.8 V. A key part of the circuit is the rail-to-rail class-AB output stage with folded mesh feedback control that combines power efficiency with operation down to 1.8 V and allows s...

A new form of magnetically coupled DC/DC converter is proposed for medium power applications (250 W to 2 kW), requiring a high-voltage gain, short inductive charging time and galvanic isolation. The proposed converter can be realised using a unique Y-source impedance network and a two-switch push–pull circuit with voltage-doubling rectification. The converter’s voltage gain is presently not mat...
