The course introduces the fabrication technologies and the function of the main digital devices which compose the modern electronic systems. Particular emphasis is devoted to field programmable gate arrays (FPGA) and their configuration though VHDL language. Main topics include: planar CMOS and bipolar transistor technology, integrated capacitor and resistor. Static and dynamic RAM, FIFO, EEPROM and FLASH. Numerical systems, fixed and Block Floating point mathematical operations in logic circuit
