Abstract :
A simple scheme to boost the supply voltage above and below the supply rails is introduced. Three applications of this technique are discussed: a) a rail-to-rail sample and hold circuit operating from a single supply voltage close to a transistor´s threshold voltage; b) a low-voltage rail-to-rail switch for high precision applications; c) a NAND gate capable of operating with a single supply voltage close to one half of a transistor´s threshold voltage. Experimental results from prototypes in 1.5 μm CMOS technology are shown that verify the proposed approach.
