ABSTRACT:
The disclosed invention is a programmable gain feedback amplifier consisting of a high gain (op-amp) amplifier, feedback elements and fuse networks in the feedback and/or input paths, a decoding circuit for receiving an input programming command signal, and thereby selectively blowing (or opening) the proper fuses to establish the desired signal attenuation in said networks. After programming, the gain of the amplifier circuit is related to the total attenuation of the network(s), is permanently set, and does not require the programming signal to be continuously applied. Embodiments are described which are compatible with monolithic microelectronic fabrication techniques.
