Item type:Publication, 0.5-V High Linear Fully Differential Multiple-Input Bulk-Driven OTA With Effective Self-Embedded CMFB(2024-01-01); This paper presents a new fully differential multiple-input operational transconductance amplifier (FD MI-OTA) with an effective self-embedded common-mode feedback circuit (CMFB). The circuit employs several design techniques to extend the linearity to the rail-to-rail level, such as a bulk-driven, multiple-input capacitive voltage divider and source degeneration. The circuit uses self-cascode transistors to increase the gain of the OTA from one side and to create a common-mode feedback circuit, needed to control the common-mode output voltage from the other side. Thus, the CMFB is part of the OTA and as a result, its chip area and power consumption remain unchanged. The performance of the proposed circuit was simulated using TSMC s CMOS 0.18 μ m process in the Cadence Virtuoso System Design Platform to validate the performance of the topology. Intensive simulation results based on Monte Carlo and process, voltage, temperature corners were performed to confirm the OTA's performance and the robustness of the CMFB. The circuit operates with a supply voltage of 0.5 V and consumes 17.5nW of power, making it suitable for applications with extremely low voltage supply and low frequency. As an application, a second-order low-pass filter was designed based on the proposed FD MI-OTA. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Electronically tunable current-mode high-order ladder low-pass filters based on CMOS technology(2015-01-01); Abuelma'atti, Muhammad TaherThis paper describes the design of current mode low-pass ladder filters based on CMOS technology. The filters are derived from passive RLC ladder filter prototypes using new CMOS lossy and lossless integrators. The all-pole and Elliptic approximations are used in the proposed low-pass filter realizations. The proposed two types of filter can be electronically tuned between 10 kHz and 100 MHz through bias current from 0.03 μA to 300 μA. The proposed filters use 1.5 V power supply with 3 mW power consumption at 300 μA bias current. The proposed filters are resistorless, use grounded capacitors and are suitable for further integration. The total harmonic distortion (THD) of the low-pass filters is less than 1% over the operating frequency range. PSPICE simulation results, obtained by using TSMC 0.18μm technology, confirm the presented theory. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Log-domain all-pass filter-based multiphase sinusoidal oscillators(2013-04-01); Wongprommoon, NatapongLog-domain current-mode multiphase sinusoidal oscillators based on all-pass filters are presented in this paper. The first-order differential equation is used for obtaining inverting and non-inverting all-pass filters. The proposed oscillators are realized by all-pass filters whose natural frequency and stage gain can be electronically tuned by adjusting the bias currents. Each all pass filter contains 10 NPN transistors and a grounded capacitor. The validated BJT model which is used in SPICE simulation operated by a single power supply as low as 2.5 V. The frequency of oscillation can be controlled over four decades. The total harmonic distortions of these MSO at frequency 56.67 MHz and 54.44 MHz, obtained around 0.52% and 0.75%, respectively. The proposed circuits enable fully integrated in telecommunication systems and also suit to high-frequency applications. Nonideality studies and PSpice simulation results are included to confirm the theory. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Integrable CMOS-Based Current-Mode Sinusoidal Frequency and Peak Detector(2017-12-01)This research proposes the integrable CMOS current-mode instantaneous frequency and peak detector (FPD) based on the trigonometric relationships and mathematic algorithm without the divider function and low-pass filter. The proposed FPD structure is straightforward, consisting of two differentiators, two multipliers and one square-rooter. The input of FPD is operable in the 20–100 kHz frequency and 20–100 μ A amplitude under ± 1.5 V power supplies. In the research, the FPD was simulated using the current-mode CMOS technology and a prototype detector subsequently materialized using the commercially available components. In addition, the FPD was experimentally utilized as the FM and AM demodulators with very satisfactory demodulation outcomes. The simulation and experimental results were agreeable and also consistent with the trigonometric relationships and algorithmic scheme. More importantly, the integrable FPD could achieve the high-accuracy current output and fast response. - Some of the metrics are blocked by yourconsent settings
