“…Figure 12 c demonstrated the results of PPF for this bilayer device. PPF is always investigated to provide adjustment for conductance in order to perform short-term neural behaviors such as synaptic filtering and adaptation [ 156 , 157 ]. During two continuous pulse stimulations of their Ag/SiO x :Ag/TiO x /p ++ -Si samples, the next post-synaptic response became higher than that of the previous one, which indicated that the interval time of spike was less than the recovery time.…”

Resistive random access memory (RRAM) devices are receiving increasing extensive attention due to their enhanced properties such as fast operation speed, simple device structure, low power consumption, good scalability potential and so on, and are currently considered to be one of the next-generation alternatives to traditional memory. In this review, an overview of RRAM devices is demonstrated in terms of thin film materials investigation on electrode and function layer, switching mechanisms and artificial intelligence applications. Compared with the well-developed application of inorganic thin film materials (oxides, solid electrolyte and two-dimensional (2D) materials) in RRAM devices, organic thin film materials (biological and polymer materials) application is considered to be the candidate with significant potential. The performance of RRAM devices is closely related to the investigation of switching mechanisms in this review, including thermal-chemical mechanism (TCM), valance change mechanism (VCM) and electrochemical metallization (ECM). Finally, the bionic synaptic application of RRAM devices is under intensive consideration, its main characteristics such as potentiation/depression response, short-/long-term plasticity (STP/LTP), transition from short-term memory to long-term memory (STM to LTM) and spike-time-dependent plasticity (STDP) reveal the great potential of RRAM devices in the field of neuromorphic application.

In this paper we proposed a novel enhanced gate diffusion (EGDI) adder is designed and is implemented in Distributed Arithmetic (DA) based Finite Impulse Response (FIR) filter. Generally multipliers, adders and shift accumulators are the basic blocks present in the FIR filters. The hardware architecture of multipliers is very high. To get rid of this, multiplier less architecture are needed in FIR filter. So Distributed Arithmetic architecture place a key role in FIR filters which will occupy less area and increase the speed. To reduce the area further the adders in DA are designed using enhanced gate diffusion (EGDI) which increases the operation speed of FIR filter and at same time the area will be decreased. The proposed design is synthesized and implemented in Synapsis design compiler tool. The area, power delay product, frequency, area delay product and power of the proposed design are calculated. When we observe the synthesis results, the proposed design has 15% high frequency rate when compare with the existing design. Also the proposed design is more useful in signal processing applications like decision feed-back equalizer.

“…[53] suggested modified DA method where Carry Look Ahead based adder tree (multiplexer-based structure) allows reuse of MAC blocks for memory locations reduction and better area-delay product. A high speed and low power FIR filter is presented in [52] where author proposed offsetbinary code (OBC) DA for reconfigurable filter design with shared LUT updating method.…”

Hearing is one of the most crucial sense for human beings as it connects them to external world. Hearing loss impairs communication which is an essential human function. Hearing disability has massive negative impact on life, work, physical and emotional well-being as well as relationships and is rated as the third most common health problem affecting relations and quality of life. Hearing aid devices can selectively intensify sound signals in order to suit the hearing characteristics of the patients and is a boon for people with hearing misfortune. However, there is a huge gap between the potential and actual hearing aid users. This work provides a critical look into the various challenges posed by hearing aid users, the comparative of the existing state-of-art hearing devices and throws light on bottlenecks in hearing aid design and performance. Filter bank, being the holy grail of Digital Hearing aid, needs special attention for improving the hearing aid performance. Reconfigurability is the need of the hour for providing flexible and tailormade hearing aids that can suit individual hearing requirements. The paper discusses and gives an in-depth insight into the techniques for reconfigurable Filter bank design for performance augmentationin terms of parameters like Signal quality, Auditory compensation, Computational and Hardware complexity, area, speed, power, etc.
