4450C
Here the internal op-amp of the EL4450C replaces the
external amplifier. The feedback capacitor CF does not
provide a perfect integration action; a zero occurs at a
frequency of 1/2RCF. This is canceled by including
another RCF pair at the AGC control output. If the refer-
ence voltage must be negative, the resistor at pin 11 is
connected to ground rather than the reference and pin 10
connected to the reference.
The amplitude reference will have to support some AC
currents flowing through R. If this is a problem, several
changes can be made to
eliminate it. The reference is connected to pin 10 and the
resistor R connected to pin 11 reconnected to ground,
and one of the multiplier input connections are reversed.
Square-law detectors have a restricted input range, about
10:1, because the output rapidly disappears into the DC
errors as signal amplitudes reduce. This circuit gives a
multiplier output that is the absolute value of the input,
thus increasing range to 100:1:
