Abstract
A device and method for dc isolation and level shifting includes a driver circuit powered by a first voltage range, a capacitor connected to the driver circuit, and a latching circuit connected to the capacitor. The latching circuit is powered by a second voltage range and is configured to restore and/or minimize charge loss of the capacitor during a voltage transition at the capacitor. A device and method for analog isolation and measurement configured to measure an analog voltage at a second potential without requiring analog circuits at the second potential.
