چکیده
Energy harvesters with higher power and direct-current (DC) output are of great significance for the energy supply electronic devices. Here, we demonstrate rotary disk multi-phase freestanding-electret generators (MFEGs) enhanced low ripple via a novel design. This design can enhance by reduction generator capacitance improvement transferable charge density through positively utilizing edge effect. The factors which both theoretical experimental results show that two- three-phase FEGs have maximum than conventional single-phase FEG (SFEG) two-phase (TFEG) has highest one. To further improve power, optimize structural parameters TFEG obtain 78.4% optimal SFEG in experiment. Moreover, MFEGs connected to rectifier bridges almost DC outputs. And since each phase is independent, be utilized separately, example, one as sensing signal other output, providing broad prospect self-powered sensing.

متن کاملA Low-Power Multi-Phase Oscillator with Transfer Gate Phase Coupler Enabling Even-Numbered Phase Output
We propose a transfer gate phase coupler for a low-power multi-phase oscillator (MPOSC). The phase coupler is an nMOS transfer gate, which does not waste charge to the ground and thus achieves low power. The proposed MPOSC can set the number of outputs to an arbitrary number. The test circuit in a 180-nm process and a 65-nm process exhibits 20 phases, including 90◦ different angles. The designs...
متن کاملAnalysis of output ripple in multi-phase clocked charge pumps
This paper presents a mathematical analysis of the ripple voltage caused by a mismatch in parasitic capacitances in multi-phase, clocked charge pumps. Through detailed circuit modeling, we show that a relatively large pedestal ripple is caused by a small mismatch in parasitic capacitance. We present a simple circuit solution and verify its performance with simulation and experimental results.

We propose a phase-locked loop (PLL) architecture which reduces double frequency ripple without increasing the order of loop filter. Proposed architecture uses quadrature numerically–controlled oscillator (NCO) to provide two output signals with phase difference of π / 2 . One of them is subtracted from the input signal before multiplying with the other output of NCO. The system also provides s...
