The last basic configuration is the Square Root as shown in
Figure 5. Here feedback is provided to both X and Y inputs.
The Balance equation takes the form of Equation 11:
Which equates to Equation 12:
The four basic configurations (Multiply, Divide, Square and
Square Root) as well as variations of these basic circuits
have many uses.
Frequency Doubler
For example, if ACos(
ωτ) is substituted for signal A in the
Square function, then it becomes a Frequency Doubler and
the equation takes the form of Equation 13:
And using some trigonometric identities gives the result in
Equation 14:
Square Root
The Square Root function can serve as a precision/wide
bandwidth compander for audio or video applications. A
compander improves the Signal-to-Noise Ratio for your
system by amplifying low level signals while attenuating or
This provides for better low level signal immunity to noise
during transmission. On the receiving end, the original signal
may be reconstructed with the standard Square function.
Communications
The Multiplier configuration has applications in AM Signal
Generation, Synchronous AM Detection and Phase
Detection to mention a few. These circuit configurations are
useful in applications that require high speed signals on all
inputs.
