A boostless 7T static random access memory SRAM cell with high writability, improved stability and reduced read failure is proposed. The proposed 7T utilises feedback cutting during write operation, which does not require a boosted supply for single access transistor. This technique enhances the writability of the SRAM cell at ultra-low voltage (ULV) supply without any write assist at 90 and 20 nm technology nodes. The proposed 7T SRAM cell has write trip point (WTP) at 85.25 mV, whereas 5T fails to write ‘1’. The mean to sigma ratio (µ/σ) is improved by a factor of 1.08× and 7.14× for hold static noise margin (HSNM) and read margin, respectively, as compared to standard 5T at 300 mV in UMC 90 nm process technology. This also saves 26.41% read and 22.72% write power as compared to 5T SRAM cell at 300 mV. Moreover 7T also shows an improvement of 2.91% in HSNM and 1.85% in read margin by using FinFET technology. © 2015 Informa UK Limited, trading as Taylor & Francis group.

An ultra-broadband analog correlator consisting of a four-quadrant multiplier and an ultra-fast resettable integrator using only NPN transistors was designed, fabricated, and measured. For the integrator, a cross-coupled transistor pair is used as a negative resistance generator. A novel ultra-fast reset circuit is implemented which allows to reset the integrator within very short time of 120 ps. The chip was fabricated using 130 nm SiGe BiCMOS technology with fT of 250 GHz and fmax of 300 GHz. In the measurements carried out on printed circuit board, the correlator operated without noticeable performance degradation with inputs up to 33 Gbps which correspond to a bandwidth of more than 24 GHz. The correlator exhibits high linearity with output P1dB of more than 9.9 dBm (700 mVdiff) for both inputs. It dissipates 122.5 mW for the core circuit excluding the 50 Ω output driver. To the knowledge of the authors, the circuit represents the fastest analog correlator published so far. It can be used for spread spectrum communication, radar signal processing, and measurement applications. © 2016 IEEE.

This paper reports a novel approach to modify a microfluidic chip by hybrid molding of small pieces to the inner wall of PDMS microchannel exposing the surface of the pieces. In this research, we employed a LSI chip and a microfabricated chip as an embedded piece. Addition of intermediate material between a piece to be embedded and a mold prevent a functional surface of the piece from possible coverage with PDMS. Agarose gel showed the best performance as such intermediate material. The use of the optimal amount of agarose successfully embedded a bare LSI chip as a functional piece into the inner wall of PDMS microchannel without wraparound or moat. This research enables us to fabricate microfluidic chips of complicated hybrid structure with various sensors as chip at low cost. © 2016 The Institute of Electrical Engineers of Japan.

The high sensitive pH image sensor is required in biology and cytology field. In our previous work, highly sensitive pH sensor, which is capable to measure 0.01pH, with a Q-trap structure had been fabricated. However, two-dimensional array sensor couldn't be realized due to large threshold voltage variability between each pixel. In this study, a multi ICG measurement method was proposed for ion image sensor with high pH sensitivity. The method was a measurement procedure to reduce the threshold voltage variability by controlling V_(ICG) at each pixel. A 16k pH image sensor with the Q-trap was fabricated. We successively took a ion image with small pH difference using multi ICG system.

Single ended data sensing for asymmetrical low voltage memories has become a topic of much interest due to its application in very low energy computing and communication. In this paper, we present an ultra-high-speed (UHS) data sensing scheme for single ended near threshold asymmetric static random access memory (SRAM) design in a 45nm standard CMOS process. The proposed bit-line decoupled single ended sense amplifier (BD-SESA) deactivate a low-V th latch by fixing the gate of NMOS device to ground (gnd) which makes the proposed scheme vulnerable to wrong latching for bitline offset due to process variation. We rigorously investigated the impact of process, voltage and temperature (PVT) variation on sensing delay, standby leakage and sensing failure and achieved commendable improvement in power dissipation and sensing delay. A self shut-off mechanism (SSM) significantly reduces voltage swing at read bit-line (RDBL) which further results in reduced power dissipation. Extensive post-layout simulation has verified that our design is insensitive to bit-line capacitance and achieves sensing delay of 297.7pS and 411.7pS at 1V and 0.8V supply respectively and offers 52.56% and 60.36% better mean with 61. 3% and 19.7% less silicon area than designs in comparison.

Experimental evaluation of navigation algorithms requires physical robots as well as position sensing devices. The common alternative is to use simulations to run the experiments. However, simulation often does not provide an accurate prediction of real-world behavior. Therefore, in this paper, we present an innovative approach towards evaluation of navigation algorithms, which does not need physical robots and position sensors to be present at the experimenter's site, but relies on a special remote internet-accessible physical testbed, the “Teleworkbench”, which can be used in order to evaluate as well as uniformly cross-compare algorithms with no need of spending money on hardware or simulation software. More specifically, in this paper we are using the Teleworkbench to evaluate three different path planning algorithms, and compare it with simulation. Different metrics are proposed, such as the path execution time, smoothness and path clearance deviations. Our results clearly illustrate the superiority of the Telework-bench as an evaluation platform in comparison to simulation, which does not provide an accurate prediction of actual physical performance, and thus illustrate both the viability as well as the power of our novel approach.
