<p>A videoamplifier including at least one transistor amplifying circuit (T1, T2, 10, 18, 20) which is designed in such a way that the transistors (T1, T2) will exhibit a linear characteristic in a range of small variations of the input signal (Vi) and a hard switching characteristic in response to large input signal variations. Due to this circuit design, the output signal (Vo) will, in general, be proportional to the input signal (Vi) but will be able to respond more quickly to a sudden increase of the input signal.</p> |
