Abstract
A direct coupled linear amplifier which employs negative feedback to prov accurate and stable gain to AC as well as DC input signals. It also performs the function of a DC level shifter and can therefore be interfaced with a variety of signal sources. A constant current source added to the summing junction of the negative feedback amplifier enables the adjustment of the DC level of the output and the AC gain of the amplifier, completely independently of one another.
