The performance of high-power converters employing silicon controlled rectifiers (SCRs) operating at several kilovolts and switching several thousands of amperes is strongly dependent on the triggering circuit and the protecting circuit (snubber) used. In this paper two standalone trigger circuit topologies are discussed and test results are given for one of them in particular, built with off-t...

Because microwave products in the consumer electronics market are continuous developing, device and component manufacturers have to seek new advanced integration, packaging and interconnection technologies, as size, cost and performance are critical factors for the success of a microwave product. One of the most promising integration technologies is the multilayer low temperature co-fired ceram...

In this paper, a new trans-admittance-mode biquad filter configuration based on two multi output voltage differencing transconductance amplifiers (MO-VDTAs) as newly active elements is proposed which also consists of two grounded MOS resistors and two capacitors with one of the capacitor is being permanently grounded. The proposed configuration is competent of realizing trans-admittance-mode lo...

In this study, the single chamber microbial fuel cell (MFC) with annular configuration and spiral anode geometry is proposed for future large-scale applications. Dairy wastewater containing complex organic matter was used as substrate. Factors affecting power generation and internal resistance of this MFC such as substrate injection, electrode surface area, and substrate concentration were inve...

Energy Recovery Battery Testing Systems (ERBTS) plays an important role in battery manufacture. The conventional ERBTS configuration contains a fundamental transformer, and a bidirectional Direct Current (DC)–DC and Alternating Current (AC)–DC converter. All ERBTS are connected in parallel, thus constituting a special and complicated AC micro-grid system. Aiming at addressing their low energy r...

High-frequency characteristic of a TVC-input circuit becomes dominant factor in the AC-DC transfer difference at frequencies higher than 100 kHz. In order to evaluate the high-frequency characteristics of TC modules up to 1 MHz, a High-Frequency-standard TVC (HF-TVC) has been developed at AIST, in collaboration with Nikkohm Co. Ltd. The HF-TVC is designed such that the frequency characteristic ...

Field Programmable Gate Arrays (FPGAs) with supply voltage (Vdd) programmability have been proposed recently to reduce FPGA power, where the Vdd-level can be customized for FPGA circuit elements and unused circuit elements can be power-gated. In this paper, we first design novel Vddprogrammable and Vdd-gateable interconnect switches with minimal number of configuration SRAM cells. We then evalu...

It is shown that the holes of the objects in an input image with a CT-CNN [1] or a DT-CNN [2] may be obtained in a single transient using just one linear parameter configuration. A set of local rules is given that describe how a CNN with a linear configuration may extract the hole of the objects of an input image in a single transient. The parameter configuration for DT-CNNs or for CT-CNNs is o...
