A low-voltage operational capability near 1 V along with low noise and distortion characteristics have been realized in a passive sigma-delta modulator. To achieve low-voltage operation, the dc voltage in signal paths in the switched-capacitor-filter section was set to be 0.2 V so that sufficient gate-to-source voltages were obtained for metal-oxidesemiconductor (MOS) switches in signal paths w...

Switch-mode voltage regulators are considered as the dominant choice for low-power integrated power supplies. Employing the advantages of a switch-mode voltage regulator in 0. 18μm CMOS technology, a power supply has been designed for a complete System-on-Chip (SoC). While offering enough drive capability for the entire system, the supply provides an extra highly-regulated output for noise-sens...

In this paper a novel very high performance current mirror is presented. It favorably benefits from such excellent parameters as: Ultra high output resistance (36.9GΩ), extremely low input resistance (0.0058Ω), low output (~0.18V) and low input voltage (~0.18V) operation, very low power consumption (20μW), very low offset current (1pA), ultra wide current dynamic range (150dB), and ultra high a...

The camera stabilizer stabilizes the camera’s line of sight by isolating the camera from the model uncertainties, disturbances of operating environment and system movements. This paper presents a voltage-base optimal adaptive fuzzy sliding mode control for camera stabilizer. In this proposed control method, a voltage-base sliding mode controller is applied. But unfortunately, undesirable ...

This paper proposes a design of single input multiple output (SIMO) dc–dc converter. The proposed converter can generate the voltage of a low voltage input to controllable levels of boosted output voltage and it can also produce the inverted output voltage. This dc-dc converter utilizes the properties of voltage clamping and soft switching based on a coupled inductor. In this paper, the design ...

This paper presents a nonisolated, high boost ratio hy-brid transformer dc–dc converter with applications for low-voltage renewable energy sources. The proposed converter utilizes a hy-brid transformer to transfer the inductive and capacitive energy simultaneously, achieving a high boost ratio with a smaller sized magnetic component. As a result of incorporating the resonant operation mode into...

The LM5032 dual current mode PWM controller contains all the features needed to control an interleaved boost converter. The two outputs operate 180 degrees out of phase and have separate current limit inputs for each channel. In addition to a high input voltage range, the controller contains all the auxiliary features needed to control a complete converter. Introduction A basic boost converter ...

A BiCMOS temperature stable voltage-tofrequency converter is described. The circuit includes an input voltage-to-current conversion stage followed by a voltage-controlled current switch. The switch is controlled by a nonsaturated multivibrator with a limiter of the output voltage swing. The multivibrator thresholds are stabilized using a current produced in a bandgap voltage reference. This all...

Abstract: Four-switch synchronous buck-boost (FSBB) converter is much suitable for battery management system for its characteristic of wide input voltage range, high efficiency, and positive voltage output. A three mode control scheme with two modulation signals and one carrier can be adopted to achieve the smooth transition among modes. Using feed forward voltage mode control, the input voltag...
