发明名称 Cascoded level shifter protection
摘要 A cascoded level shifter for receiving an input signal in a low voltage range and for generating an output signal in a high voltage range is disclosed. The cascoded level shifter is subdivided into a first voltage section and a second voltage section, the first voltage section having a lower voltage supply than the second voltage section, and a combined voltage across the first voltage section and the second voltage section corresponding to the high voltage range, the cascoded level shifter comprising: an input node configured to receive an input signal; a cascoded device disposed in one of the first voltage section and the second voltage section, the cascoded device comprising a driver switch connected in series with a cascode switch at a midpoint node, the cascode switch switching in dependence on a reference voltage of a reference node and the input signal; and reference voltage perturbation circuitry, configured to cause a transient perturbation to the reference voltage in response to a transition of the input signal to cause the cascode switch to switch.
