ABSTRACT:
A comparator (22) compares the output signal (Vout) supplied by an output amplifier (21) with an input signal (Vin). Dependent on the result of the comparison, it controls the conduction of one or the other of two sources (IGA, IGB) which supply opposite currents. Two complementary assemblies (A, B) each comprise a first transistor (T1A, T1B) and a second transistor (T2A, T2B). Each first transistor (T1A, T1B) has its base controlled by one of the current sources for charging a first capacitance (C1) connected to the output, and also controls the conduction of the corresponding second transistor. The bases of the second transistors (T2A, T2B) are jointly connected to the first capacitance (C1) and their emitters are jointly connected to the negative input of the output amplifier (21). The negative input of the output amplifier (21) is also connected to a reference voltage (Vref) via a resistor (20) and to the output (Vout) via a second capacitance (C2).
