Abstract

The demand for low-power transconductors capable of delivering linear performance is rising especially in biomedical applications. This work introduces a flipped voltage follower (FVF)-based bulk-driven (BD) double diffusor double differential pair (D⁴P) transconductor designed using 0.18 μm technology. The proposed design operates effectively at ±0.5 V, achieving a linear range of 0.2 V, transconductance (G_m) of 1.07 μS, power dissipation of 0.365 μW, gain of 27 dB, a gain-bandwidth product of 27 kHz. Further analysis reveal the figure of merits, FOM₁ and FOM₂ values of proposed transconductor are 240 and 29.38, respectively with a linearity enhancement factor of 1.7 which are quite encouraging. Monte Carlo analysis show the G_m, gain and total harmonic distortion have mean values of 1.06 μS, 26.13 dB, −47.40 dB, respectively which are close to their nominal values. The total layout area of the transconductor is 20204.54 μm², providing a compact yet effective design for low-voltage applications.

期刊介绍： Integration''s aim is to cover every aspect of the VLSI area, with an emphasis on cross-fertilization between various fields of science, and the design, verification, test and applications of integrated circuits and systems, as well as closely related topics in process and device technologies. Individual issues will feature peer-reviewed tutorials and articles as well as reviews of recent publications. The intended coverage of the journal can be assessed by examining the following (non-exclusive) list of topics: Specification methods and languages; Analog/Digital Integrated Circuits and Systems; VLSI architectures; Algorithms, methods and tools for modeling, simulation, synthesis and verification of integrated circuits and systems of any complexity; Embedded systems; High-level synthesis for VLSI systems; Logic synthesis and finite automata; Testing, design-for-test and test generation algorithms; Physical design; Formal verification; Algorithms implemented in VLSI systems; Systems engineering; Heterogeneous systems.
