  • Digitally controlled variable transconductance amplifier system
    Patent number: 5903191
    Abstract: A digitally controlled variable transconductance amplifier system including first and second input means for receiving first and second input voltages of opposite phase; first and second output means; a voltage to current converter system responsive to the input voltage and including a reference voltage to current converter and a plurality of voltage to current converters each having a different gain relative to the reference voltage to current converter such that the total gain of the voltage to current converters is less than that of the reference converter; each of the converters providing a pair of oppositely phased converter output currents; and a summing system including a reference switching circuit and a plurality of switching circuits, the reference switching circuit and the switching circuits being interconnected with said reference converter and the plurality of voltage to current converters, respectively, the summing system being responsive to a digital control signal for operating each of the swi
