Electric Power Steering (EPS) is a full electric system, which reduces the amount of steering effort by directly applying the output from an electric motor to the steering system. In this paper, the constitutions and its operational mechanism of electric power steering system, and the construction and the equivalent circuit of the DC motor used in EPS were introduced; and the EPS hardware frame...

In this paper, a low voltage CMOS current controlled floating resistor which is convenient for integrated circuit implementation is designed by using differential pair. The proposed resistor has a simple circuit structure and low power dissipation. This circuit is required ±0.75 V as a power supply.

This paper deals with the electromagnetic emissions of integrated circuits. In particular, four measurement techniques to evaluate integrated circuit conducted emissions are described in detail and they are employed for the measurement of the power supply conducted emission delivered by a simple integrated circuit composed of six synchronous switching drivers. Experimental results obtained by e...

With technology scaling, power supply and threshold voltage continue to decrease to satisfy high performance and low power requirements. In the past, subthreshold CMOS circuits have been inadequate for high performance applications, but have been used in applications that require ultra low power dissipation. Many applications including medical and wireless applications, require ultra low power ...

Deregulated wholesale markets for bulk electricity supplies are likely to deviate from the perfectly competitive ideal in many areas where transmission losses, costs and capacity constraints isolate customers from the effective reach of many generators and limit the number of competitors. In those regions where a few suppliers or marketing agents dominate the market, prices may rise wellabove t...

A voltage scaling technique for energy-efficient operation requires an adaptive power-supply regulator to significantly reduce dynamic power consumption in synchronous digital circuits. A digitally controlled power converter that dynamically tracks circuit performance with a ring oscillator and regulates the supply voltage to the minimum required to operate at a desired frequency is presented. ...

This paper proposes a new self-biased op-amp’s startup circuit design and improved bandgap core circuit for all CMOS bandgap voltage reference (BGR). In a conventional BGR circuit, the startup circuit may be designed either be required an external power on reset signal (POR) or composed of several MOS transistors for generating bias current and the bandgap core circuits has two nodes that are c...
