Abstract

A prototype 13-b 1.33-Gsps digital-to-analog con- verter (DAC) implemented in a uni que heterogeneous integration process (combining 0.45-µm InP HBT with 0.18-µm CMOS) is presented. Measured performance of greater than 70 dB SFDR is achieved across a 500-MHz bandwidth centered at 1 GHz (second Nyquist band). Heterogene ous integration enables each circuit element to be implemente d in the transistor technology best suited to the circuit functi on. Low dc power is achieved by implementing the dig
