Abstract: A radio frequency digital-to-analog converter with a programmable current output. In exemplary aspects of the invention, improved apparatus and methods for providing (i) current mirror matching, (ii) enhanced current pulse rising edge performance, (ii) reduced base voltage swing, and (iv) compensated high voltage swing, are provided. The foregoing apparatus and methods can be applied to any RF signal application (wireless or otherwise), including for example wireless cellular handsets.
