iii. a scaling resistor coupled between a least significant node conductor of the MSB ladder section and a most significant node conductor of the LSB ladder section; and (c) a plurality of switch circuits each selectively conducting a respective parallel resistor circuit to a first reference voltag...
16. A DAC current correction circuit comprising: a first current generating circuit operational to provide a replicated MSB unit source current into a R-2R ladder circuit portion of a LSB segment of a current steering DAC; and a second current generating circuit operational to provide a correctio...
Selection switches at each resistor connection point selectively connect a ladder node to an output node of the DAC based on the digital address. In implementation, the ladder DAC requires at least 2N resistors and 2N selection elements, where N is the number of bits in the digital address. ...
