Abstract
The present invention relates to a linear, high sensitivity, high speed trans-impedance amplifier (TIA) which allows a large dynamic range of input current up to very large values, maintains high linearity and keeps constant output voltage, maintains the same frequency response across the full gain control range, provides very high input sensitivity and large bandwidth, and allows input current monitoring without affecting input sensitivity. In other words, the novel circuit disclosed herein provides for the feedback path to maintain the same level of feedback even while the output signal is varied. This allows a wide and stable bandwidth, as well as a monitor to be placed in the TIA.
