  • Transimpedance amplifier with noise reduction and bandwidth compensation
    Patent number: 4855687
    Abstract: The signal-to-noise ratio of a transimpedance operational amplifier is enhanced by employing a large feedback resistor. Bandwidth lost in the process recaptured by a compensation network without reducing the signal-to-noise ratio. The compensation network provides a zero which cancels the upper 3 db pole of the transimpedance amplifier, and also provides a high frequency pole defining the restored bandwidth of amplifier.
