+/- 0.45 V CMOS Second-Generation Voltage Conveyor Based on Super Source Follower
Yesil, Abdullah; Minaei, Shahram; Psychalinos, Costas (Springer Birkhauser, 2021)A simple ultra-low-voltage realization of second-generation voltage conveyor (VCII) based on the employment of super source follower, as voltage follower, and of current follower is presented in this paper. Full CMOS ... -
Design and application examples of CMOS fractional-order differentiators and integrators
Bertsias, Panagiotis; Psychalinos, Costas; Elwakil, Ahmed; Safari, Leila; Minaei, Shahram (Elsevier Sci Ltd, 2019)Reduced complexity CMOS fractional-order differentiator and integrator building blocks are introduced in this work, based on 2nd-order integer-order transfer function approximations. These blocks are then used for implementing ... -
Fractional-Order and Power-Law Shelving Filters: Analysis and Design Examples
Kapoulea, Stavroula; Yesil, Abdullah; Psychalinos, Costas; Minaei, Shahram; Elwakil, Ahmed S.; Bertsias, Panagiotis (Ieee-Inst Electrical Electronics Engineers Inc, 2021)Low-pass and high-pass non-integer order shelving filter designs, which are suitable for acoustic applications, are presented in this work. A first design is based on a standard fractional-order bilinear transfer function, ... -
Fractional-order differentiators and integrators with reduced circuit complexity
Bertsias, Panagiotis; Safari, Leila; Minaei, Shahram; Elwakil, Ahmed; Psychalinos, Costas (IEEE, 2018)Fractional-order differentiation and integration stages are essential building blocks for performing signal processing using fractional-order calculus. One important characteristic of fractional-order differentiators/integrators ... -
Two-quadrant fully integrable rms-to-dc converter for handling low-frequency signals
Minaei, Shahram; Psychalinos, Costas (Elsevier, 2015)A novel current-mode rms-to-dc converter architecture is introduced in this paper. It is constructed from a current squaring stage and a lowpass filter with low cutoff frequency realized using the concept of Log-Domain ... -
Ultra low-power electronically tunable current-mode instrumentation amplifier for biomedical applications
Psychalinos, Costas; Minaei, Shahram; Safari, Leila (Elsevier, 2020)In this paper, a new current-mode instrumentation amplifier with electronic tuning and low-voltage operation capabilities is presented. Simplicity is other important feature so that the whole circuit is composed of only ... -
