Operational Amplifier Design with Rail to Rail Supply Voltage Output Having Reduced Power Dissipation

In this paper design for 1 volt rail to rail supply voltage output of operational amplifier with common mode feedback amplifier has been presented. The circuit has been simulated using BSIM4 model with 50nm CMOS process. The simulation results show that output voltages for the modified operational amplifier are swinging from 10mV to 990mV i.e. between the rail to rail supply voltages (0 to 1V)....

Optimisation of Reliability of Power Supply to Consumers

An approach of solution of the problem of consumers’ power supply reliability is presented. The electric power systems is assumed operating in a market environment.

A High Efficiency Power Supply with High Power Factor Input

This paper presents a single-stage ZVT full-bridge AC/DC converter for aerospace applications. The detailed operating principle and design consideration of this soft-switched converter are analyzed and described. The proposed circuit topology and control scheme are proposed to exhibit optimum performances (i.e. high power factor, high efficiency, ring-free and low EMI features). A laboratory pr...
