This paper describes an implementation of a compact and low-power 10-bit Floating-Gate Digital-to-Analog Converter (FGDAC). Nonvolatile Floating-Gate voltage references are utilized to build a charge amplifier DAC architecture. This novel implementation eliminates the large element spread and resolution trade-off in the traditional design of charge amplifier voltage-output DACs. The FGDAC was fabricated in a 0.5µm CMOS process and its total area is 0.0522mm 2 . The presented experimental data
