| 摘 要： | 提出了一种用于14位250 MS/s ADC的数据发送器。该发送器输出采用电流模驱动方式,最高数据传输速率达3.5 Gb/s,数据输出仅需要2个数据端口。电路采用180 nm 1.8 V 1P5M CMOS工艺实现。测试结果表明,该发送器在3.5 Gb/s速率下的输出信号摆幅为800 mV,抖动峰峰值为100 ps,功耗为32 mW。采用该3.5 Gb/s数据发送器的ADC在250 MHz采样率下得到的信噪比为71.1 dBFS,无杂散动态范围为77.6 dB。

| Abstract: | A transmitter for 14-bit 250 MS/s ADC was presented.A high speed current mode driver was used in the transmitter, which could achieve a data rate of 3.5 Gb/s, and needed only two digital output ports. The proposed circuit was fabricated in a 1.8 V 180 nm 1P5M CMOS technology. Tested results showed that the differential eye opening was 800 mV, the peak-to-peak jitter was about 100 ps, and the power consumption was 32 mW at the data rate of 3.5 Gb/s. The ADC that adopted the 3.5 Gb/s transmitter had achieved a signal-to-noise ratio of 71.1 dBFS and a spurious free dynamic range of 7.6 dB at full sampling speed. |
