Abstract
Disclosed is a voltage generator that includes a first voltage generation circuit and a second voltage generation circuit. The first voltage generation circuit is selectively operable in a single trimming mode enabling positive trimming only or in a dual trimming mode that shifts the voltage range downward enabling a somewhat smaller amount of positive trimming and also some negative trimming. The second voltage generation circuit is selectively operable in a single trimming mode enabling negative trimming only or in a dual trimming mode that shifts the voltage range upward enabling a somewhat smaller amount of negative trimming and also some positive trimming. Also disclosed is an integrated circuit (IC) chip that incorporates one or more such voltage generators for back-biasing the field effect transistors in one or more circuit blocks, respectively.
