  • Transimpedance amplifier (TIA) circuit and method
    Patent number: 9030263
    Abstract: A TIA circuit and method are provided that merge the automatic gain control function with the bandwidth adjustment function to allow the TIA circuit to operate over a wide dynamic range at multiple data rates. The TIA circuit has an effective resistance that is adjustable for adjusting the gain and the bandwidth of the TIA circuit. The mechanism of the TIA circuit that is used to adjust the effective resistance, and hence the gain and bandwidth of the TIA circuit, is temperature independent, and as such, the performance of the TIA circuit is not affected by temperature variations.
