To improve the capacity and coverage of current cellular networks, many advanced technologies such as massive MIMO, inter-cell coordination, small cells, device-to-device communications, and so on, are under studying. Many proposed techniques have been shown to offer significant performance improvement. Thus, the enabler of those techniques is of great importance. That is the necessary signalin...

This work presents a low-voltage, low power CMOS symmetrical operational transconductance amplifier (OTA) and its application for realization of a biopotential amplifier in neural recording application. The linear range of OTA is increased by employing multi-tanh differential configuration and source degeneration while the commonmode range is enhanced using DC-shifting scheme. The proposed symm...

In this paper, a low Power, Gain Boosted Recycling Folded Cascode Operational Transconductance Amplifier (GB-RFC OTA) is described. The proposed GB-RFC OTA is designed using 130nm CMOS technology and achieves enhanced gain, unity gain bandwidth and slew rate with the low Power budget. The proposed circuit operates on 1V supply voltage and 200 μA bias current and consumes a power of 798μW.The GB...

In this paper, a general two-admittance current-mode circuit structure using Dual-Output OTA (DO-OTA) is explored to derive new third-order unsymmetrical band-pass filters. The proposed circuits are attractive as they require less number of OTAs and use only grounded capacitors. The other advantageous features offered by proposed filters are ease of design, good sensitivity and orthogonal tunab...

background ochratoxin a (ota) is a toxic secondary metabolite produced by fungi belonging to aspergillus and penicillium genera. the production of ota is influenced by environmental conditions and nutritional requirements. the postharvest application of bunches of table grape fruit (tgf), with water activity of 0.8 aw, was highly effective for controlling ota contamination in vitro and in vivo ...

this paper investigates the relationship between the lagos megacity and ota township, a small township onits periphery. the study examines linkages between and lagos in terms of growth, urban development as well as mobility. 553 questionnaires were administered to household heads across the 12 residential districts of ota township. survey was carried out by systematic random sampling. classifie...
