A CMOS circuit for approximately tripling battery voltage particularly adaptable for use with liquid crystal displays such as used in watches. P-wells of the CMOS circuit are coupled to active circuit nodes rather than to battery potentials. In the presently preferred embodiment a hybrid circuit with external capacitors is used to increase overall efficiency.
