The internal components of a 741 opamp are shown below.
The circuit is divided into three stages. The input stage consists of ideal transistors, Q1 and
Q2, and associated sources and passive elements. It produces the linear and nonlinear
differential mode (DM) and common mode (CM) input characteristics. The capacitor,
C
e,
introduces a second order-effect for the slew rate and C1 introduces a second-order effect to
the phase response.
