PROBLEM TO BE SOLVED: To provide a method for determining a switching threshold and associated electronic circuitry for implementing the method. SOLUTION: The present invention provides electronic circuitry for converting an input voltage signal (401) at a first voltage level into an output signal (402) at a second voltage level. An output unit (203) is disposed for outputting the output signal (402) using an output of the electronic circuitry. On the other hand, an input unit (101) is provided for inputting the input voltage signal (401) at the first voltage level. A threshold comparison unit (104) is effective in comparing the first voltage level of the input signal (101) with a switching threshold (404). COPYRIGHT: (C)2008,JPO&INPIT
