摘要：
An integrated circuit has a pseudosubstrate 6060 with an isolation moat 9505. Substrate 6001 has one conductivity and a subcircuit region 6060 has an opposite conductivity. Digital CMOS devices are formed in the subcircuit over region 6060 and operate between zero to +5 volts. Analog devices are formed over the rest of the substrate and operate between plus and minus 5 volts. The moat 9505 isolates the digital CMOS devices from the analog devices.
