This paper describes a 12-bit 100kS/s successive approximation register analog-todigital converter (SAR ADC) for biomedical system. Both top-plate sampling technique and VCM-based switching technique are applied to the capacitor digital-to-analog converter (CDAC) to implement a 12-bit SAR ADC with 10-b capacitor array DAC. To enhance the linearity of proposed ADC, thermometer decoder is used in...

This paper presents an Inductive Power Transfer (IPT) system design using a Class E converter circuit. The Class E converter is used to drive a nonlinear load and theoretically it offers 100% efficiency. To be specifically, the performance of IPT system at 1MHz operating frequency and 9V DC supply voltage is analyzed. Voltage doubler rectifier and Darlington circuit are proposed in this paper t...

Forward converters generally exhibit poor power factor when employing in the AC-DC conversion, due to the presence of zero input current near the zero crossing of line input voltage. In this paper, a single-switch forward converter with high power factor and low storage capacitor voltage stress is proposed. By adding a stack up voltage on top of the reflected input voltage on the forward conver...

In this paper, there is a combined approach which is used to compensate three stage amplifiers with ultra large capacitive loads and low power, using current mirror amplifier with split output is to decrease the occupied level of compensation capacitor that causes to lessen the occupied level of chip –area for using compensation capacitor and getting resulted in the light of better slew rate (S...

Between the metal–insulator–metal (MIM) capacitor and metal–oxide–metal (MOM) capacitor, the MIM capacitor has a better characteristic of stable capacitance. However, the MOM capacitors can be easily realized through the metal interconnections, which does not need additional fabrication masks into the process. Moreover, the capacitance density of the MOM capacitor can exceed the MIM capacitor w...

The future trends in microprocessor supply current requirements represent a bottleneck for next generation highperformance microprocessors since the number of supply pins will constitute an increasingly larger fraction of the total number of package pins available. This leaves few pins available for signaling. On-chip power conversion is a means to overcome this limitation by increasing the inp...

A new multi-device wireless power transfer scheme that reduces the overall charging time is presented. The proposed scheme employs the intermediated energy storage (IES) circuit which consists of a constant power driving circuit and a super-capacitor. By utilizing the characteristic of high power density of the super-capacitor, the receiver can receive and store the energy in short duration and...

The various optimal capacitor placement techniques on transmission and distributions lines for line losses reduction and enhancement of voltage stability in the power system network have been proposed so far in different papers. Optimal Capacitor placement is an optimization problem which has an objective to define the sizes and locations of capacitors to be installed. This paper focuses on the...

In the most recent heuristic methods, the high potential buses for capacitor placement are initially identified and ranked using loss sensitivity factors (LSFs) or power loss index (PLI). These factors or indices help to reduce the search space of the optimization procedure, but they may not always indicate the appropriate placement of capacitors. This paper proposes an efficient approach for t...
