Operational Transconductance Amplifier (OTA) is an amplifier which uses the differential input voltages and generates the output current. Therefore, it can be called as a voltage controlled current source. OTA is an important building block in designing of continuous time analog filters. Existing trend in continuous scaling down of the transistor size and reduction in power supply have added to the...
The emergence of the internet of everything (IoE) demands high-performance, real-time multi-media and wideband networking in battery-operated mobile systems. For this reason, higher bandwidth and lower power mobile DRAMs are becoming increasingly critical. As promising candidates of next-generation mobile DRAM, the development of LPDDR4 [1] and wide-IO2 (WIO2) DRAM is ongoing these days. The conventional...
In this paper, we present a low power consumption and high gain low noise amplifier using transformer feedback to neutralize the gate-source and gate-drain overlap capacitance of a FET. It is a single-ended amplifier designed in 65nm CMOS technology for 60 GHz transceiver. This LNA achieves a simulated gain of 10.64 dB, noise figure of 3.10 dB at 60 GHz.
Regular expression (regex) matching is an essential part of text analytics and network intrusion detection systems. The leftmost longest regex matching feature enables finding a leftmost derivation of an input text and helps resolve ambiguities that can arise in natural-language parsing. We show that leftmost longest regex matching can be efficiently performed in a dataflow pipeline by combining a...
The Mobile intermittent wireless connectivity limits the evolution of the mobile landscape, such that this progress coupled with the ubiquitous nature of the Internet and the web services. The web service Reliability achieves the low overhead communication and retrieves the appropriate state response from the web service consumption. This paper discusses and analyzes the most recent approaches that...
In this paper, a new low voltage very high performance quasi-floating gate based current mirror is proposed. The proposed current mirror combines the high accuracy, very low input resistance and extremely high output resistance characteristics of low voltage all cascode current mirror with wide bandwidth characteristics of quasi-floating MOSFET. It also increases the output resistance offered by the...
Today's residential Internet service is bundled and shared by a multiplicity of household devices and members, causing several performance problems. Customizing broadband sharing to the needs and usage patterns of each individual house has hitherto been difficult for ISPs and home router vendors. In this paper we design, implement, and evaluate a system that allows a third-party to create new services...
IPv6 addressing schemes for networks consisting of power constrained wireless sensor nodes require special consideration to reduce the time and traffic required for a node to join the network. Here we explore several existing models of IPv6 address allocation schemes for this use case. We offer a novel approach to reduce the chance of address duplication via a hierarchical manipulation of the host...
A two-stage Miller-compensated amplifier with Gm-boosting (MCG) is introduced in this paper. The design involves the conventional two-stage amplifier and a proposed wide-bandwidth scalar circuit that amplifies the output signal voltage at the first stage of the conventional two-stage amplifier. The wide-bandwidth scalar circuit has very short delay so that the non-dominant pole and right-half-plane...
This paper presents a two-stage sub-threshold current mirror, bulk-driven OTA, which utilizes reverse nested Miller and feed-forward frequency compensation techniques to ensure stable operation, while driving widespread capacitive loads from 1 pF up to 1 nF. This two-stage OTA provides a 60 dB open loop gain, 25 kHz gain bandwidth, 82° phase margin and 91 dB common mode rejection ratio driving 15...
Smart homes provide unique information platform with different communication technologies including both licensed and unlicensed frequency bands. The number of these small cells is forecast to become huge, which eliminate the traditional network deployment and operational techniques. At present, the internet access of a smart home is dependent on the unreliable customer broadband connection for its...

Point to multipoint multicast (MC) packets delivery without optimal distribution trees is prone to unnecessary retransmissions that adversely influences narrow-band VHF networks. The bandwidth efficient MC packet delivery path has to be calculated to best reach all destinations using the inherent broadcast nature of VHF radio subnets by avoiding retransmissions of the same message/packet in the same...
The special communication scenario in High-Speed Train (HST) not only leads to an increasing demand of high throughput and continuous multimedia services but also arises many other challenges for cellular network access technology, such as high mobility, frequent and group handovers etc. In order to address above problems, we propose an HST WiFi network application scheme which adopts multi-hop technology...
TSVs can be fabricated with pitch of only tens of μm, and smaller. They can be densely distributed as inter-die interconnect in 3D ICs. However, the huge mismatch between the probe technology, such as the pitch of probe head and the capacity of probe card, and the TSV fabrication technology leads to an insufficient probe on TSV tips. In this paper, we present a novel TSV probing technique that can...
This paper presents a universal down conversion mixer for a multistandard wireless receiver with adapted reconfigurability in the form of RF bandwidth, active/passive and IF bandwidth. In the proposed architecture RF bandwidth reconfigurability is reconfigured between low band (LB) RF frequency and high band (HB) RF frequency mixer modes. LB / HB reconfigurability is made through power switching the...

Special protection schemes (SPS) have been implemented by many utilities to maintain power system integrity. Successful operations of SPS depend on reliable sensors, actuators, controllers and data processing units involved. In the past, if performance analysis of SPS is conducted, only the reliability of processing and decision systems is considered assuming that the data needed for correct operations...
Intrinsic noise has been predicted as a limit to CMOS scaling. If this is the case, the effect would be more severe at low supply voltages, such as the ones applied in subthreshold digital circuits. In this work the effect of intrinsic noise in subthreshold digital nanoscale CMOS is analysed for the first time. Key issues such as variability and the actual bandwidth of the studied circuits are taken...
