Abstract

In previous work the PPA was shown to behave more optimally with a load resistance which was much lower than normally used in the common optical wireless receiver-amplifiers, such as the High Impedance- or Transimpedance type. This paper discusses the use of a zero bias mode combined with low load impedance, which results in further enhancements in receiver performance. An optimised load is usually a pure resistance, typically several ohms, giving around 8.6 dB improvement in gain over a 50 Ω standard load impedance, but output impedance matching to 50 Ω can permit a similar optimum gain over a wider range of frequencies.
