摘要:
An integrated circuit provides high voltage isolation capabilities. The circuit includes a first area containing a first group of functional circuitry located in a substrate of the integrated circuit. This circuit also includes a second area containing a second group of functional circuitry also contained within the substrate of the integrated circuit. Capacitive isolation circuitry located in the conductive layers in the integrated circuit provide a high voltage isolation link between the first group of functional circuitry and the second group of functional circuitry. The capacitive isolation circuitry distributes a first portion of the high voltage isolation signal across the first group of capacitors in the capacitive isolation circuitry and distributes a second portion of the high voltage isolation circuitry across the second group of capacitors in the capacitive isolation circuitry.
