The output of a linear op-amp circuit has the same shape as the
input signal. If the input is sinusoidal, the output is sinusoidal. At no
time during the cycle does the op amp go into saturation. This chapter
discusses a variety of linear op-amp circuits including inverting
amplifiers, noninverting amplifiers, differential amplifiers,
instrumentation amplifiers, current boosters, controlled current
sources, and automatic gain control circuits.
