摘要
采用非复位结构,在SMIC0.18μm CMOS工艺下,设计并实现了一种采样/保持电路,其性能满足10位精度、100MS/s转换速率的ADC的要求.电路在0~125℃,三种工艺角下仿真,其性能均满足要求;T/H电路的核心—OTA,经流片并测试,结果表明其功能正确,功耗与仿真值一致。
Using non-reset architecture, a take/hold circuit for 10 bit 100 MS/s ADC is implemented in SMIC 0.18 μm CMOS process. Simulation result proved the implementation. The core of T/H eireuit-OTA is fabricated. The measured results have shown that the OTA works fluently and the power consumption is near that simulated.
