In this paper a complete implementation and design of fully-synthesized 32-bit microcontroller in 130nm CMOS technology is presented. This the first featuring open source RISC-V instruction set all mounted through AXI4-Lite APB buses for communication process. The contains 10-bit SAR ADC, 12-bit DAC, an 8-bit GPIO module, 4kB-RAM, SPI AXI slave interface output verification, checking correct behavioral bridge. All peripherals are controlled by master that used programming device data flowing...
Modern systems-on-chip use multiple current sources to guarantee appropriate circuit biasing according the required performance and power consumption. Here we review efforts select design practical implementations of references depending on target domain. Although several options are available address architectural choice, few traditional reference always preferred. In this work, extend standard bandgap-based applications requiring reliable accurate references. Measurement results across...
This paper deals with new power flow formulations for AC distribution networks. The problem is approximated using Laurent's series expansion method over the product between voltage variables in balance equations, which proportionates a mathematical structure similar to conventional Newton-Raphson method. proposed model developed complex variables, decreases number of calculations needed and prevents transformation load into polar coordinates. Numerical results confirm that faster regarding...
