摘要:

采用数字化端子控制技术,基于负反馈动态调整原理和可调多晶硅电阻条,设计了新颖的、符合高速串行接口USB2.0协议要求的高精度片上匹配电阻电路.使用TSMC的CMOS 0.25μm混合信号模型,在Cadence软件环境下用spectre仿真器模拟,结果表明在500 MbPs的高速时钟信号作用下,所设计的匹配电阻阻值在[44.3 Ω,45.6 Ω]范围内,最大稳定时间6μs,平均误差为±1.45%,所设计电阻平均变化范围为45×(1±1.45%)Ω,最大误差范围1.56%,达到并高于45×(1±10%)Ω的高速串行接口协议要求.

Abstract:

Using digital terminal control technology, based on the principle of negative feedback dynamic adjustment and adjustable polysilicon resistance strip, a novel high-precision on-chip matching resistor circuit that meets the requirements of high-speed serial interface USB2.0 protocol is designed.Using TSMC’s CMOS 0.25μm mixed-signal model and simulated with spectre simulator in the Cadence software environment, the results show that under the action of 500 MbPs high-speed clock signal, the designed matching resistance value is [44.3 Ω. In the range of 45.6 Ω], the maximum settling time is 6μs, the average error is ±1.45%, the average variation range of the designed resistor is 45×(1±1.45%)Ω, and the maximum error range is 1.56%, which meets and exceeds the high-speed serial interface protocol requirements of 45× (1±10%)Ω.
