Applications
Voltage Controlled Amplifiers
For optimum signal-to-noise performance, I
large as possible as shown by the Output Voltage vs. Ampli-
fier Bias Current graph. Larger amplitudes of input signal
also improve the S/N ratio. The linearizing diodes help here
by allowing larger input signals for the same output distortion
as shown by the Distortion vs. Differential Input Voltage
graph. S/N may be optimized by adjusting the magnitude of
the input signal via R
below some desired level. The output voltage swing can
then be set at any level by selecting R

Although the noise contribution of the linearizing diodes is
negligible relative to the contribution of the amplifier’s inter-
nal transistors, I
mizes the dynamic junction resistance of the diodes (r
