<p>A current-limited differential entry stage compares an input signal (IN) to a reference voltage (V ref ) generated by a current-limited transistor or diode configuration (E6, E7). Current limiters comprise a D-mode feedback transistor (D2; D3) having a gate-source junction, the D-mode transistor not conducting between the source and the drain if a gate-source voltage is larger negative than a negative threshold voltage, and conducting between the source and the drain else,and a feedback connection (13; 23) connecting the source of the D- mode feedback transistor to its gate via a component that generates a voltage drop (E4, E5; E8, E9).</p> |
