However, a negative feedback amplifier can be unstable such that it may oscillate.
A line amplifier (100) is provided that employs two diplex filters (110, 140) each connected to both a forward and reverse amplifier (120, 130).
A reference voltage and the gate winding voltage are applied to a feedback amplifier (44) in the feedback circuit (42).
An input signal supplied through an input terminal (IN) is amplified by an NFB amplifier (10) and is output from an output terminal (OUT).
The variable impedance circuit (11) provides negative feedback to the NFB amplifier (10).
A bootstrap technique (Q3) is utilized to enhance the amplification of the bipolar amplification stage.
Since the detector sense node is 'pinned' by the feedback amplifier, reset noise is reduced to that generated by the much smaller feedback capacitance.
A variable impedance circuit (11) including a diode is connected between the input and output of the NFB amplifier (10).
