Performance evaluation of low-voltage silicon and GaN power FETs is presented for chip-scale DC-DC power converter applications. The circuit calculations are based on an improved circuit model for the FET with accurate description of terminal capacitances and on-resistance. It is shown that GaN power FETs combined with silicon MOS power diodes can potentially lead to nearly 82% power conversion efficiency...
Detailed performance evaluation of silicon and GaN power FETs is presented for chip-scale DC/DC converter applications. It is shown that improved GaN power FETs and silicon MOS power diodes can potentially lead to nearly 90% power conversion efficiency when switched at 5 MHz in a synchronous buck converter topology.
We demonstrate electrically functional 0.099 μm2 6T-SRAM cells using full-field EUV lithography for contact and M1 levels. This enables formation of dense arrays without requiring any OPC/RET, while exhibiting substantial process latitudes & potential lower cost of ownership (single-patterning). Key enablers include: 1) high-k/metal gate FinFETs with Lg˜40 nm, 12-17 nm wide Fins, and cell β ratio...
This paper presents the design of a voltage controlled oscillator (VCO) for multi-standard wireless receiver covering global standards for mobile (GSM), digital communication systems (DCS), personal communication systems (PCS), and universal mobile telecommunication system (UMTS) standards. An effective frequency planning scheme that requires the VCO to tune from 3.2 GHz to 4.1 GHz and generate multiple...
