Abstract
Transimpedance amplifiers with improved gain-bandwidth products. The transimpedance amplifiers include a boost current circuit to increase the gain-bandwidth product of the transimpedance device, particularly useful when using low voltage power supplies. The boost current can be made responsive to the input current of the amplifier, better accommodating large input currents. The boost current may also be responsive to the power supply voltage, reducing the boost current with increasing power supply voltage. Various embodiments are disclosed.
