10.2.1 Design Requirements

Design a high-bandwidth, high-gain, voltage amplifier with the design requirements listed in Table 1. An inverting amplifier configuration is chosen here; however, the theory is applicable to a noninverting configuration as well. In an inverting configuration the signal gain and noise gain transfer functions are not equal, unlike the noninverting configuration.
