ABSTRACT:
Methods and circuits for minimizing or eliminating the effect of trimming circuits in a voltage generating circuit are provided. In general, the effects of channel resistance of switches of the trimming circuit are reduced by utilizing switches in series with the output, rather than in parallel with resistors, as in conventional trimming circuits. Because the switches are not in parallel with the resistors, when the switches are turned on, no channel resistance is added to the effective resistance controlled by the trimming circuit.
