| Abstract: | A high speed ,wideband operational amplifier is presented in the paper ,which is based on bipolar process. Considerations are specified dealt with on wideband ,high speed design of the circuit architecture. Through the computer,simulation and measurement results are given. After verified fabricated chips, the designed operational amplifier meets the expected specification. The result is satisfied. This circuit finds wide applications in video amplifiers, active filters, high speed data conversions and other electronic systems. |
