Abstract
A level converter for the converting of a first digital signal (U ) having a first voltage range into a second digital signal (U ) having a second voltage range comprising an amplifier (T ) having an input for receiving the first digital signal (U ) and an output for supplying the second digital signal (U ), a series arrangement for controlling the slew-rate of the second digital signal (U ) which comprises at least a first capacitor (C ) and a second capacitor (C ) and which is coupled between the output and the input of the amplifier (T ), and voltage controlling means for controlling the voltages (V , V ) across the at least first and second capacitors (C , C ). The voltage controlling means comprises at least one voltage source (V , V ) for supplying a separate bias voltage to each internal node (N , N ) of the series arrangement. The value of the separate bias voltage or the values of the separate bias voltages is/are dependent on the values of the first (U ) and the second (U ) digital signals.
