A nonvolatile static random access memory (NVSRAM) cell with two back-up CuxO memory devices is proposed in this paper. The manufacturing process is compatible with the standard CMOS process. By adopting a dynamic supply voltage scheme, the proposed cell can work correctly in four different operation modes. Compared with the standard SRAM cell, the proposed cell offers non-volatile storage which allows...
Performances of AlGaN/GaN HFETs have much improved recently and very high potential of this heterostructure for high power and high frequency electronic devices has been verified. Application of new device technologies such as field plate, recessed gate, digital pre-distortion circuit and dual field plate was essential to realize such high device performances both at 2 GHz, 5GHz and 26 GHz. However,...
Large current carrying capabilities of AlN/GaN/InN based heterostructures and high breakdown voltages make this materials system uniquely suited for applications in high power and/or high frequency electronic devices, including power amplifiers, broadband amplifiers, power switches, and radio frequency switches. AlGaN/GaN insulated gate transistors have additional advantages of extremely low leakage...
To improve the bSPIFET, the SA-bSPIFET which used self-aligned process had been proposed. However there are many characteristics of bSPIFET not yet be studied. This paper focuses on the misalignment of gate shift (GS) in a 30 nm bSPIFET. Based on 2D simulation, the misalignment of GS will influence the electrical characteristics causing the degradation of the short channel behaviour and the stability...
Advancement of field programmable gate array (FPGA) faces many challenges. Among the major ones are power management and high speed transceiver I/O demands. To overcome the challenges, process-design co-optimization is required. With co-optimization of process, circuit, and architecture, 45% static power reduction is achieved for a 40 nm FPGA design. With optimized analog devices, high data rate (8...
