Current Mode Four Quadrant Multiplier
pending current in, current out four quadrant multiplier. Input
and output signal summing and direct interface to other
current mode devices can be accomplished by simple
connection to reduce component count and preserve
bandwidth. The selection of an appropriate series resistor
value allows an input to accept a voltage signal of any size
and optimize dynamic range. The differential outputs offer
significant performance improvements which greatly extend
the usable gain control range at high frequencies. The bias
current is programmable to accommodate the voltage and
power dissipation constraints of the package and available
systems supplies.
The devices can implement all the classic four quadrant
multiplier applications and are uniquely well suited to gain
control and signal summing of broadband signals.
