ABSTRACT:
A voltage-current amplification circuit comprises two sub-circuits (B1, B2), each of which comprises a differential amplifier (D), a resistor (R4), a transistor (T), and a first switch (K1) connected between the transistor base and ground. Each sub-circuit (B1, B2) also comprises an additional amplifier (A1, A2), and an additional resistor (R2a, R2b), respectively. The inputs of the additional amplifiers being connected to ground through a common resistor (R) and to the emitters of the two transistors through a common resistor (R1). Each sub-circuit further comprises a second switch (K2) formed by a single transistor.
