Operational-amplifiers


Posted on Jun 9, 2012

This is a single gain-of-100 amplifier with a gain-bandwidth product of 20 MHz! The primary limitation in the performance is the low slew rate (0.3 VIJ1s) imposed by IoH charging CcoMP· The effects of slew rate and compensation are shown. A lower gain amplifier requires a larger CcoMP, which in turn further reduces slew rate. For this reason, it might actually be advantageous in certain areas to lower the gain by placing a resistive divider at the input rather than raising R1.
