Wideband Four-Quadrant Multiplier

Figure 4. Absolute-Value Input Circuitry

An ECL comparator produces an output corresponding

to the sign of the input, which when multiplied by the

input produces an effective

absolute-value function. The RC product connected to

the X inputs simply emulates the time delay of the com-

parator to maintain circuit accuracy at higher

frequencies.
