10.2.4 Arbitrary Waveform Generation (AWG)

Arbitrary waveform generation circuits are common in memory and semiconductor test equipment. These circuits are used to generate reference ac waveforms to test semiconductor devices. The key performance parameters of such circuits are THD, SNR, and the update rate. Figure 65 shows the basic building block example of an AWG circuit using the DACx1001.
