FIGURE 2(a) shows the Bode plot of op-amp THS4021. The
manufacturer describes this device as a ââ?¬Ë?decompensated op-ampââ?¬â?¢, by
which is meant that the frequency compensation is partial as opposed to
ââ?¬Ë?uncompensatedââ?¬â?¢ where no compensation is used at all. The advantages
of ââ?¬Ë?decompensationââ?¬â?¢ over ââ?¬Ë?full compensationââ?¬â?¢ include a higher open-loop
gain and better slew rate. Greater care, however, is needed in the use of
such an op-amp as frequency stability cannot be assured.
