چکیده
Multiple voltage conversion ratio (VCR) recursive switched-capacitor (SC) dc–dc converters, based on several basic 2:1 are widely used for on-chip power supplies due to their flexible VCRs higher energy efficiency. However, conventional multiple VCR SC converters usually have one or more unused some VCRs, which results in lower density and chip area wastage. This article presents a new converter system, can dynamically reconfigure the connection of all cells so that designs be reused this architecture increasing load-driving capacity, density, To validate design, 4-bit-input 15-ratio system was designed fabricated 180-nm BCD process, support maximum load current $\text{0.71}\,\text{mA}$ achieves peak efficiency 93.1% with notation="LaTeX">$105.3\,\mu \text{A/mm}^{2}$ from 2-V input supply. The measurement show capacity become 6.826×, 2.236×, 2.175× larger than topology when is 1/2, 1/4, 3/4, respectively. In addition, under these specific also improved considerably.

Recent advances in low-power circuits have enabled mm-scale wireless systems [1] for wireless sensor networks and implantable devices, among other applications. Energy harvesting is an attractive way to power such systems due to limited energy capacity of batteries at these form factors. However, the same size limitation restricts the amount of harvested power, which can be as low as 10s of nW ...

متن کاملResonant Switched Capacitor DC-DC Converter with Stackable Conversion Ratios
As the demand for fully integrated power management system has increased in recent years, the switched-capacitor (SC) converter has shown exceptional promise due to the favorable energy density of capacitors, but its limited output range and its intrinsic charge-sharing loss have limited its range of applications. In this paper, a resonant switched-capacitor (ResSC) topology is presented as a w...

A Recursive Switched-Capacitor (RSC) topology is introduced that enables reconfiguration among conversion ratios while achieving minimal capacitive charge-sharing loss for a given silicon area. All ratios are realized by strategically interconnecting 2:1 SC cells either in series, in parallel, or in a stacked configuration such that the number of input and ground connections are maximized in or...
