ABSTRACT:
The invention proposes a negative gain transconductance amplifier circuit (1) for capacitive load that includes:an RC serial circuit connected between an input terminal (E) of the amplifier circuit and a intermediate terminal (A);an amplification level connected between the intermediate terminal and an output terminal (S) designed to be connected to a capacitive load, and which includes:a first negative gain transconductance amplifier (2) connected via open loop between the intermediate terminal and the output terminal;a second negative gain transconductance amplifier (3) with characteristics that are notably identical to those of the first amplifier, connected via closed loop; its input and output are connected to the intermediate terminal via a resistance (R1).
