Patent ID: 8867668

Claim:
A feed forward restore network to forward an input data signal to an amplifier circuit portion, the network comprising: an input terminal for receiving an input data signal with encoded data information; a low gain path for conducting the input data signal from the input terminal to an amplifier circuit portion, said low gain path providing a specified attenuation to the input data signal; a high gain path for conducting the input data signal substantially undistorted from the input terminal to the amplifier circuit portion; and wherein when the input data signal is above a specified level, the high gain path is deactivated and the signal passes through the low gain path; when the input data signal is below the specified level, both the low gain path and the high gain path are active and the data input signal passes through both the low gain path and the high gain path; and the feed forward restore network further comprises a passive resistive network to forward a low frequency drift compensation signal from the input terminal to the amplifier circuit portion to compensate for low frequency variations in the input data signal and to develop a desired bias voltage at the amplifier circuit portion.
