Abstract
Techniques are disclosed for a level shifter configured to adjust current flow in response to measured current fluctuations due to common mode noise in the level shifter. For example, the level shifter includes a low-side control circuit configured to adjust a first current flowing into a first low-side terminal of an active high voltage level shifter device in response to a difference between the first low-side current and a second low-side current flowing into a second low-side terminal of an inactive high voltage level shifter device. The level shifter further includes a high-side receiver circuit configured to detect a difference between a first high-side current flowing into a first high-side terminal of the active high voltage level shifter device and a second high-side current flowing into a second high-side terminal of the inactive high voltage level shifter device.
