Multiplication of analog signals has long been one of the
most important nonlinear functions of analog circuit technology.
Many signal sources, however, such as CCD sensors,
pin diodes, or antennas, deliver weak, oscillating, and
simultaneously wide-band signals. But now a new multiplication
method is available. Used as a wide-bandwidth Automatic
Gain Control (AGC) application circuit, the integrated
circuit OPA660 varies its own gain to change the signal
amplitude and keep the output signal constant over a wide
input voltage range. The OPA660 thus makes it possible to
control and amplify signals with no additional multiplier.
Important parameters include the differential gain (DG), the
thermally induced pulse distortion, and the signal-to-noise
ratio (S/N).
