Abstract
A high precision clipping regulator circuit includes a first protection diode, a second protection diode, a first offset clamp voltage regulator, and a second offset clamp voltage regulator. The first protection diode is configured to conduct when a voltage potential exceeds a first protection voltage magnitude, and is operable to exhibit variations in the first protection voltage magnitude. The second protection diode is configured to conduct when a voltage potential exceeds a second protection voltage magnitude, and is operable to exhibit variations in the second protection voltage magnitude. The first reference and second voltage regulator circuits are configured to determine when the first and second protection voltages vary and, in response thereto, to vary the first and second variable offset clamp voltages so that a difference in voltage across the protection diodes remains substantially constant.
