Measurement of Dynamic Parameters of High-Speed and High-Resolution A/D Converter Based on 93000 ATE

Based on Verigy 93000 ATE,an 11-bit A/D converter,AD80141,with an input signal up to 400 MHz was measured using external high performance crystal oscillator and RF generator.Test results showed that,for input signal frequency below 140 MHz,the measured SNR value was only less than 1 dB from target value,and for input frequencies up to 300 MHz and 400 MHz,the measured SNR were 59.46 dB and 57.03 dB,respectively.
