DIGITAL-TO-ANALOG CONVERTER CIRCUITRY WITH WEIGHTED RESISTANCE ELEMENTS

摘要

Digital-to-analog converter circuitry is described. The digital-to-analog converter circuitry includes a plurality of weighted resistance elements. A first weighted resistance element includes a switch coupled to a reference voltage. The first weighted resistance element also includes a T-network coupled to the switch. The T-network approximately equalizes a first response speed of the first weighted resistance element with a response speed of a differently weighted resistance element.
