ABSTRACT:
An amplifier topology suitable for amplification of the frequency dependent output of a transducer to provide a frequency equalized amplifier output includes a first transconductive stage for converting a voltage input signal to the current domain through a signal node and a second transreactive stage for converting the signal current into an output voltage. An active equalization network feeds back a representation of the output signal to the signal node in such a way that the fed back signal voltage error is not affected by the high impedance thereat to provide error correction feedback that is achromatic with frequency and, accordingly, does not vary across the range of frequencies amplified, to provide the second amplifier with a frequency independent closure ratio, while not reducing second amplifier voltage gain.
