研究混合信号集成电路中衬底噪声耦合反衬底噪声对模拟/数字电路的影响。采用带外延层的重掺杂型衬底,对混合信号集成电路中研究衬底噪声的两个基准(Benchmark)电路进行了模拟和评价,提出了在高速和高频工作时应用SPICE对混和信号电路进行模拟的正确方法.
The influence of substrate noise coupled anti-background noise on analog / digital circuits in mixed signal integrated circuits is studied. By using the heavily doped substrate with epitaxial layer, two benchmarks for the study of substrate noise in mixed signal integrated circuits are simulated and evaluated. The application of SPICE to mixed signals at high speed and high frequency is proposed. The correct way to simulate the circuit.
