This work presents a voltage mode scheme of a full-wave precision rectifier circuit using an analog building block differential voltage current conveyor transconductance amplifier (DVCCTA) including five NMOS transistors. The proposed design is essentially suited for low voltage and high-frequency input signals. The operation of the proposed rectifier design depends upon the region of operation of NMOS transistors. The output waveform of the presented rectifier design can be made electronically tunable by controlling the bias voltage. The functional correctness and verification of the presented design are performed using 0.25-µm TSMC technology under the supply voltage of ±1.5 V. The absence of a resistor leads to a minimal parasitic effect. To obtain further insight on the robustness of the circuit, a Monte Carlo simulation and corner analysis are also presented. The circuit is verified experimentally by incorporating a breadboard model with the help of commercially available ICs CA3080 (operational transconductance amplifier) and AD844AN (current feedback operational amplifier) and offers remarkable compliance with both theoretical and simulation outcomes. The presented design has been laid out on Cadence virtuoso, which consumes a chip area of 9044 µm2.

“…More specifically, pump TENG provides charges for the whole system, and charge transferring induces a current in the circuit. The current is then rectified by a full‐bridge rectifier (FBR, also named full‐wave rectifier, [ 59 ] FWR) or a VBC (also named VMC, [ 57 ] ), to inject separated charges of opposite signs into two conduction domains mentioned above. Due to the changeable overlapped area between two electrodes of main TENG along with the sliding movement, its capacitance varies correspondingly while that of buffer capacitor stays constant, leading to a voltage difference between them.…”

processing, and transmission of information. [1][2][3] Moreover, portable and wearable electronics for health monitoring and interactive communication are already widespread in our life. [4,5] Accordingly, the demanding energy for powering these electronics soars with time, especially the distributed and low-powered energy sources. [6,7] At present, the vast majority of power sources for needed electricity are different batteries, [8][9][10] which are widely used owing to their mature processing technology and low manufacturing cost. However, the batteries have the inherent drawbacks of a limited lifetime and capacity. [11,12] And there are some knotty problems of environmental pollution and recycling difficulty [13,14] when wearing out. Therefore, much effort has been devoted to exploring other types of sustainable and green energy sources like solar energy, wind energy, etc., which serve as a complement or replacement. [15] Since invented by Wang et al. [16] in 2012, the triboelectric nanogenerator [17][18][19][20] (TENG) has become the spotlight among researchers with great promising potential to be the following generation of energy. Based on the coupling effects of electrostatic induction and triboelectrification, [21][22][23] the TENG has merits of high efficiency, easy fabrication, various materials, and low cost. [22,[24][25][26] It has witnessed great progress and achievements in micro-nano energy, [27][28][29][30] self-powered systems, [26,[31][32][33][34][35][36][37][38] blue-ocean energy, [39][40][41][42] and high voltage applications. [43][44][45][46][47][48] However, there are some challenges to face for TENG, such as the ultrahigh but unstable voltage (about several thousand volts) and the relatively low current (about microamperes), which greatly hinder its practical applications in daily life of IoT. Meanwhile, as the static charges being fully constrained on dielectric surfaces, the TENG has quite little induced charge transferring in the circuit and low charge density on the surfaces, [49] which limits its power output.To improve the performance of TENG in energy supply, some previous researches have focused on structure optimization, [50,51] material selection, [52] surface modification, [53] and environment control. [54] Through the corona charging, Zhou et al. [55] have enhanced the charge density to 240 µC m −2 . By highly packaged in vacuum, an ultrahigh charge density of 1003 µC m −2 is obtained by Wang et al., [54] yet leading to great difficulty for the device fabrication. Recently, the emerging contact-separated charge pump technology brings with a new bright prospect and a breakthrough to the bottleneck of charge As an emerging harvester for mechanical energy, the ultrahigh and unstable voltage and low surface charge density have limited the practical applications of triboelectric nanogenerators (TENGs). Herein, a charge pumping technology is demonstrated for sliding-mode TENG with voltage stabilization and enhanced current by utilizing unfixed shuttling charges to generate electricit...

A full‐wave rectifier based on a modified voltage differencing transconductance amplifier‐MVDTA and four n‐MOS transistors (or inverting full‐wave rectifier), with no use of any passive elements is proposed in this paper. The proposed design is suitable for a low voltage and high frequency input voltage/current signal. The used MVDTA possesses certain new connections without any changes in the original circuit resources of VDTA. The proposed configuration possesses satisfactory zero crossing performance, excellent linearity, low component count―a simple and compact structure―which makes it an adequate candidate for implementation in the form of IC circuits. The amplitude‐waveform of the current/voltage rectified signal at the output of the proposed circuit can be electronically controlled by the applied bias currents. The influence of possible non‐ideality and parasitic effects was analysed, while the effects of the parasitic are only marginal due to the absence of any passive elements. To verify the validity of the presented circuits, SPICE simulations deploying 0.18 μm CMOS technology parameters and supply voltage of ±0.9 V are reported, fully consistent with the theoretical predictions. The noise and Monte Carlo analyses were also performed in order to obtain further insight into the robustness of the proposed design. The proposal is also supported by experimental results in order to confirm the workability of the proposed solution.
