Instead, general-purpose amplifiers will continue to be limited to about a 1-MHz bandwidth, and special-purpose amplifiers will be built for fast applications. Such circuits as voltage followers and ...

4. An improved multiple-input op-amp summer can be analyzed more easily than the one in Figure 3. This is because the general design equation can be expressed more simply (Equation 4).

Current‐mode amplifiers have emerged as a highly efficient alternative to traditional voltage‐mode systems, particularly in high frequency and low power electronic applications.
