A major problem in an isolated DC/DC converters operating at high switching frequencies is the attendant switching losses in the semiconductor devices. This can be reduced by introducing either zero-voltage switching (ZVS) or zero-current switching (ZCS) of the semiconductor switches. This paper deals with the simulation, design, fabrication and experimental evaluation of a novel soft-switching...

We propose capacitively driven low-swing global interconnect circuit using a receiver that utilizes magnetoelectric (ME) effect induced magnetization switching to reduce the energy consumption. Capacitively driven wire has recently been shown to be effective in improving the performance of global interconnects. Such techniques can reduce the signal swing in the interconnect by using a capacitiv...

In this paper an analytic approach to estimate the nonlinearity of radix-4 pipelined analog-to-digital converters due to the circuit non-idealities is presented. Output voltage of each stage is modeled as sum of the ideal output voltage and non-ideal output voltage (error voltage), in which non-ideal output voltage is created by capacitor mismatch, comparator offset, input offset, and finite ga...

We demonstrate a small foot print (600 nm wide) 1D silicon photonic crystal electro-optic modulator operating with only a 50 mV swing voltage and 0.1 fJ/bit switching energy at GHz speeds, which are the lowest values ever reported for a silicon electro-optic modulator. A 3 dB extinction ratio is demonstrated with an ultra-low 50 mV swing voltage with a total device energy consumption of 42.8 fJ...

A new low-power design method based on multiple low swing internal voltage values is proposed in this paper. It can be applied in logic circuits, which are designed with different logic family techniques such as Complementary Pass Transistor Logic (CPL), Domino Logic and Cascade Voltage Switch Logic (CVSL). The goal of this method is the reduction of the circuit power dissipation, with only a n...

Series stacking of multiple devices in power amplifiers is a promising technique that has been explored recently at millimetre-wave frequencies to overcome some of the fundamental limitations of metal–oxide–semiconductor (CMOS) technology. Stacking multiple devices improve the output power and efficiency by increasing the achievable output voltage swing. Switching power amplifiers (PAs), such a...

Hydropower plays a key role in the actual energy market due to its fast response and regulation capacity. In that way, hydraulic turbines are increasingly demanded to work at off-design conditions, where complex flow patterns and cavitation appear, especially in Francis turbines. The draft tube cavitation surge is a hydraulic phenomenon that appears in Francis turbines below and above its Best ...

This research paper explains the effect of dimensions Gate-all-around Si nanowire tunneling field transistor (GAA Si-NW TFET) on ON/OFF current ratio, drain induces barrier lowering (DIBL), sub-threshold swing (SS), and threshold voltage (VT). These parameters are critical factors characteristics tunnel transistors. The Silvaco TCAD has been used to study electrical TFET. Output (gate voltage-d...

In this paper we present an on-chip noise detection circuit. In contrast with the previous works concerning on-chip noise measurement, this detector does not assume specific noise properties such as periodicity. The detector is able to continuously capture 10 nano-second time window from the measured signal with a resolution equal to 100 pico-second. The requested bandwidth of the output channe...

A high performance monolithic 4:1 analog multiplexer implemented in an 8 GHz dielectrically isolated complementary bipolar process was designed and simulated. It is useful in many general purpose high-speed applications such as driving an 150 Q cable or an analog to digital (A/D) converter. This switched transconductance amplifier 4:1 video multiplexer has a current mode decoder, a voltage feed...
