ABSTRACT:
A wide bandwidth amplifier is coupled to the differential output of a four-quadrant multiplier. The amplifier includes a differential to single-ended input stage driving the inverting input of an operational amplifier which has its noninverting input operating at a reference potential level. The amplifier output is coupled by way of a level shifting means to the circuit output terminal which is thereby referenced to ground potential. The circuit output terminal is returned through a resistor to a source of opposite polarity power supply so that the output terminal can swing above and below ground. The second supply is only connected by way of the output terminal so that it does not require an extra package pin.
