Design of a 10-bit 100MHz Pipelined ADC Using 0.25μm CMOS Process
【摘要】 采用流水线结构完成了一个10位精度100MHz采样频率的模数转换器的设计。该模数转换器采用采样保持电路、8级1.5位和最后一级2位子模数转换器的结构,电路使用全差分和开关电容电路技术。芯片采用台积电(TSMC)0.25μmCMOS工艺,电路典型工作电压为2.5V,在室温下,输入信号为5MHz,采样频率100MHz时信号噪声失真比为59.7dB。
【Abstract】 A 10-bit, 100 Msamples/s pipelined ADC was presented. It was composed of a sample-and-hold circuit, eight stages with 1.5bit per stage, and a 2 bit flash ADC as last stage. Fully differen-tial structure and switched capacitor technology were used. The ADC’s design was based on theTSMC 0.25μm, mixed signal process. It works at 2.5V supply voltage, at room temperature, 5 MHz inputfrequency and 100MHz sampling frequency, SNDR is 59.7dB.
