    A 1.8 v 11.02 μw single-ended inverter-based OTA with 113.62 dB gain
    (Institute of Electrical and Electronics Engineers Inc., 2016) Kaliyath, Y.; Laxminidhi, T.
    This paper presents a low power 1.8 V single-ended operational trans conductance amplifier (OTA) with a very high dc gain targeted for audio applications. Cascoding and gain boosting are employed to achieve the high gain. The amplifier is implemented in UMC 180 nm CMOS technology. For a typical process corner, the amplifier provides a dc gain of 113.62 dB and a unity gain bandwidth of 2.49 MHz at 62.9° phase margin with capacitive load of 2.5 pF. The amplifier consumes only 6.12 μA of quiescent current from 1.8 V supply. The amplifier exhibits good performance across all the process corners with the use of body bias technique. © 2016 IEEE.

    Design and Analysis of Microstrip Wideband Filter
    (Institute of Electrical and Electronics Engineers Inc., 2023) Mahapatra, R.K.; Kaliyath, Y.; Shet, N.S.V.; Satapathi, G.S.; Manjukiran, B.; DImri, P.; Shetty, A.N.; Srichandan, R.; Patro, B.S.; Senapati, A.
    This paper deals with the study on conventional wideband bandpass filter (BPF) and the bandpass filter designed using the split ring resonator structure. The proposed design using the SRR consists of 3 SRR on which the filter is mounted. This is designed using the HFSS software. The material with in the dielectric constant of 4.36 and the loss tangent of 0.01 is used for the substrate material. The substrate height is varied with the dimension of 4.9 x 2.9 kept constant. The result observed for the BPF on SRR with increase substrate height has shown better results better return loss characteristics as compared to the other design. © 2023 IEEE.

    High notch microstrip antenna array at Ka band
    (Institute of Electrical and Electronics Engineers Inc., 2023) Mahapatra, R.K.; Kaliyath, Y.; Satapathi, G.S.; Shet, N.S.V.; Patra, J.P.; Manjukiran, B.; Rai, S.J.; Athmiya Raj, A.G.; Durgesh; Rai, H.
    This paper presents the experimental research and design for microstrip patch array antenna which resonates in Ka band. The proposed design consists of 4 microstrip rectangular patches. HFSS software is used for the simulation and analysis with four candidate structure. A material having a dielectric constant of 4.36 is used for the substrate material with the low loss tangent of 0.01. The dimension of the patches are varied to achieve better result. Design of all the antenna were within the range of 28 to 40 GHz. Designed Antenna exhibit the bandwidth range within 2.925 GHz to 7.7 GHz. By adjustment of the size of the patch i.e length, width and height, an appreciable gain within 9.62 dB to 9.98 dB was observed within the proposed design. The proposed antenna array will be able to scaled to a larger radiating structure. © 2023 IEEE.

    3D-Printing Technology: A Review
    (Institute of Electrical and Electronics Engineers Inc., 2024) Mahapatra, R.K.; Kaliyath, Y.; Shet, N.S.V.; Satapathi, G.S.; Mahapatro, S.R.; Lakshmu Naidu, M.L.
    The process of digital fabrication, commonly known as 3D printing, involves gradually adding materials to a geometric representation to produce actual items. The advantages of 3D printing for industrial use include little material waste, simple manufacturing, minimal human participation, minimal post-processing, and energy efficiency. In this study, we provide insights on the development of 3D printing, its history, current state, uses, and potential future directions. There is a detailed explanation of various materials that work with each sort of 3D printing procedure. © 2024 IEEE.
