Substrate isolation for analog/digital IC chips |
摘要 |
The specification describes techniques for isolating noisy subcircuits in integrated analog/digital devices. Isolation is obtained using a modification of triple well isolation wherein the deep isolation implant is restricted to the digital circuits only to prevent noise from the digital circuits from propagating to the analog sections through the buried implant. Resistor sections are also separated from the buried isolation implant.
