Abstract
A multi-level voltage generator includes P-type metal-oxide-semiconductor (PMOS) transistors that generate corresponding positive voltages and a common voltage respectively, each PMOS transistor having a source connected to corresponding generated voltage, and a drain connected to an output node to provide the corresponding generated voltage; N-type metal-oxide-semiconductor (NMOS) transistors that generate corresponding negative voltages and the common voltage respectively, each NMOS transistor having a source connected to corresponding generated voltage, and a drain connected to the output node to provide the corresponding generated voltage; and body-voltage selectors that adaptively select a body voltage for the plurality of PMOS transistors and NMOS transistors respectively, except PMOS transistor associated with a highest positive voltage and NMOS transistor associated with a lowest negative voltage with body and source connected together.
