Abstract
A wideband operational amplifier in accordance with the present invention overcomes many shortcomings of the prior art. A wideband operational amplifier may be configured to provide a high output voltage and high output current. The amplifier may comprise an input stage having a first input buffer and a second input buffer, and an output stage amplifier having an output buffer. The input stage may also include current mirrors configured to facilitate a lower input offset voltage and lower input voltage noise. Moreover, the operational amplifier may also provide a wide common-mode input range and full power bandwidth simultaneously.
