This paper describes a novel two-stage fully-differential CMOS amplifier comprising two self-biased inverter stages, with optimum compensation and high efficiency. Although it relies on a class A topology, it is shown through simulations, that it achieves the highest efficiency of its class and comparable to the best class AB amplifiers. Due to the self-biasing, a low variability in the DC gain over...
The Z-source network, as a DC-link energy storage sub-circuit, was proposed to be used in DC-AC power conversion circuits (inverters) due to its advantages compared to the traditional LC DC-link. In this paper a new modified Z-source (MZS) network is proposed in order to reduce the number of switches in a single-phase inverter, from four switches, in a full-bridge converter, to only two switches,...
