Abstract
The performance of a single-bit cell in a DAC is improved by decoupling the voltage swing across the load resistors from the output of the current steering device. This can be achieved by providing for a single-bit cell having a first load resistor R and a second load resistor R a current steering circuit, and a decoupling circuit operably coupled between the current steering circuit and the resistors R R The current steering circuit steers at least part of a current I through a circuit path towards either the first resistor R or the second resistor R The decoupling circuit decouples voltage swings across the load resistors R R from the current steering circuit.
