WebA monolithic integrated transimpedance amplifier for the receiver in a 40-Gb/s optical-fiber TDM system has been fabricated in an InP-based HBT technology. Despite its high gain (transimpedance of 2 k/spl Omega/ in the limiting mode, 10 k/spl Omega/ in the linear mode) the complete amplifier was realized on a single chip. Clear output eye diagrams … The high gain of the op-amp keeps the photodiode current equal to the feedback current through Rf. The input offset voltage due to the photodiode is very low in this self-biased photovoltaic mode. This permits a large gain without any large output offset voltage. Ver mais In electronics, a transimpedance amplifier (TIA) is a current to voltage converter, almost exclusively implemented with one or more operational amplifiers. The TIA can be used to amplify the current output of Ver mais In most practical cases, the dominant source of noise in a transimpedance amplifier is the feedback resistor. The output-referred … Ver mais The noise current of the feedback resistor equals $${\displaystyle {\overline {i_{n}^{2}}}={\frac {4k_{\text{B}}T\Delta f}{R_{f}}}}$$. … Ver mais • PIN diode • Optical communication Ver mais In the circuit shown in figure 1 the photodiode (shown as a current source) is connected between ground and the inverting input of the op-amp. The other input of the op-amp … Ver mais The frequency response of a transimpedance amplifier is inversely proportional to the gain set by the feedback resistor. The sensors which transimpedance amplifiers are used with usually have more capacitance than an op-amp can handle. … Ver mais It is also possible to construct a transimpedance amplifier with discrete components using a field effect transistor for the gain element. This has been done where a very low noise figure was required. Ver mais
