Abstract
A reference voltage generator is disclosed that may provide a plurality of reference voltages. A reference voltage generator may include a voltage divider, a multiplexer coupled to the voltage divider, an operational amplifier that may receive a voltage from the multiplexer, and a plurality of resistors that may receive an output from the operational amplifier. The reference voltages may be provided from output terminals coupled to the resistors. A reference voltage generator may include a voltage divider, two multiplexers coupled to the voltage divider, an operational amplifier coupled to each multiplexer, and a plurality of resistors coupled between the outputs of the two operational amplifiers. Reference voltages may be provided from output terminals coupled to the resistors.
