Programming floating-gate circuits with UV-activated conductances

A programming technique for controlling the floating gates (FGs) in ultra-low-voltage (ULV) floating-gate circuits is presented. Simple ULV PG current-scaling and level-shifting circuits are discussed. The current scaling and level shifting are accomplished using only minimum sized transistors and floating capacitors. Floating-gate current multiplier and divider circuits are described. Measured results are provided,.
