ABSTRACT:
A circuit arrangement in which cascaded first and second operating transistors have gate terminals connected to an input signal and a control voltage, respectively. A control path from the control voltage source to the gate terminal of the second operating transistor includes a voltage divider. First and second circuit units are also provided in the control path to selectively enable and disable the voltage divider according to a voltage level of the applied control voltage, thereby causing the circuit to have desirable control characteristics.
