We have formulated the op-amp design problem as a special type of convex optimization problem called a geometric program (GP). Open-loop gain is the gain of the op-amp without positive or negative feedback and for such an amplifier the gain will be infinite but typical real values range from about 20,000 to 200,000. Generally, op-amp function in a more linear and quieter way if some of the output signal is fed back to the negative output. Gain 8. Process specification (V T, K', C ox, etc.) Cascoding and the use of more than one gain stage are well-known techniques for boosting the gain of a CMOS op-amp [3]- Thus, for very high gain applications, a two stage cascode op-amp is an appropriate topology.
